    Consider the following statements:

    1. Deification of the Buddha
    2. Trading the path of Bodhisattvas
    3. Image worship and rituals

    Which of the above is/are the feature/features of Mahayana Buddhism?

    1. A1 only
    2. B1 and 2 only
    3. C2 and 3 only
    4. D1, 2 and 3
    Show answer

    Answer: (D) 1, 2 and 3

    The correct answer is (D) — 1, 2 and 3.

    All three are features of Mahayana Buddhism, which emerged around the 1st century AD.

    Deification of the Buddha (statement 1) — Mahayana started worshipping Buddha as a god, unlike earlier traditions that saw him as a teacher.

    The Bodhisattva path (statement 2) — Mahayana emphasizes becoming a Bodhisattva (one who delays their own nirvana to help others achieve it).

    Image worship and rituals (statement 3) — Mahayana introduced idol worship of Buddha and Bodhisattvas.

    Tip:

    • Mahayana = Buddha as God
    • Bodhisattva ideal
    • Image worship.

    Hinayana/Theravada = Buddha as teacher, no idol worship.

    Which one of the following is not a Harappan site?

    1. AChanhudaro
    2. BKot Diji
    3. CSohgaura
    4. DDesalpur
    Show answer

    Answer: (C) Sohgaura

    The correct answer is (C) — Sohgaura.

    Sohgaura (in Uttar Pradesh) is associated with an ancient copper plate inscription from the Mauryan period, NOT the Harappan civilization.

    Chanhudaro (Sindh), Kot Diji (Sindh), and Desalpur (Gujarat) are all Harappan/Indus Valley Civilization sites.

    Tip:

    • Sohgaura = Mauryan-era copper plate.
    • The other three are Harappan sites.

    Ancient and Medieval Indian History

    Consider the following statements:

    1. In the revenue administration of Delhi Sultanate, the in-charge of revenue collection was known as ‘Amil’.

    2. The Iqta system of Sultans of Delhi was an ancient indigenous institution.

    3. The office of ‘Mir Bakshi’ came into existence during the reign of Khalji Sultans of Delhi.

    Which of the statements given above is/are correct?

    1. A1 only
    2. B1 and 2 only
    3. C3 only
    4. D1, 2 and 3
    Show answer

    Answer: (A) 1 only

    The correct answer is (A) — 1 only.

    Statement 1 is correct — in the Delhi Sultanate's revenue administration, the officer in charge of revenue collection was called 'Amil'.

    Statement 2 is wrong — the Iqta system was NOT an ancient Indian institution. It was an Arabic/Islamic institution borrowed from the Caliphate and introduced in India by the Turkish rulers.

    Statement 3 is wrong — Mir Bakshi (head of the military department) was a post in Akbar's Mughal administration, NOT during the Khalji Sultanate.

    Tip:

    • Amil = revenue collector (Sultanate).
    • Iqta = Arabic system, not Indian.
    • Mir Bakshi = Mughal (Akbar), not Khalji.
    Key learnings →The Delhi Sultanate (1206-1526)

    Ancient and Medieval Indian History

    With refence to forced labour (Vishti) in India during the Gupta period, which one of the following statements is correct?

    1. AIt was considered a source of income for the State, a sort of tax paid by the people.
    2. BIt was totally absent in the Madhya Pradesh and Kathiawar region of the Gupta Empire.
    3. CThe forced labourer was entitled to weekly wages.
    4. DThe eldest son of the labourer was sent as the forced labourer.
    Show answer

    Answer: (A) It was considered a source of income for the State, a sort of tax paid by the people.

    The correct answer is (A) — It was considered a source of income for the State, a sort of tax paid by the people.

    During the Gupta period (300-600 CE), 'Vishti' (forced labour) became more common.

    It is mentioned alongside regular taxes in Gupta land grant inscriptions, which tells us that the state treated it as a form of tax — people paid with their labour instead of money.

    Tip:

    • Vishti = forced labour used as a form of taxation during the Gupta period.

    Ancient and Medieval Indian History

    In which of the following relief sculpture inscriptions is ‘Ranyo Ashoka’ (King Ashoka) mentioned along with the stone portrait of Ashoka?

    1. AKanganahalli
    2. BSanchi
    3. CShahbazgarhi
    4. DSohgaura
    Show answer

    Answer: (A) Kanganahalli

    The correct answer is (A) — Kanganahalli.

    Kanganahalli, located near Sannati in Karnataka, is the only place where the inscription 'Ranyo Ashoka' (meaning 'King Ashoka') was found alongside a stone portrait of Emperor Ashoka.

    This makes it unique because most Ashokan inscriptions use the title 'Devanampiya Piyadasi' rather than his actual name.

    Tip:

    • Kanganahalli = only site with both Ashoka's name ('Ranyo Ashoka')
    • AND his stone portrait.
    Key learnings →The Mauryan Empire

    Ancient and Medieval Indian History

    Who among the following Mughal Emperors shifted emphasis from illustrated manuscripts to album and individual portrait?

    1. AHumayun
    2. BAkbar
    3. CJahangir
    4. DShah Jahan
    Show answer

    Answer: (C) Jahangir

    The correct answer is (C) — Jahangir.

    While Akbar patronized large illustrated manuscripts like the Hamza-nama (1400 pages!), his son Jahangir shifted the focus to individual portraits and album paintings.

    Jahangir had a keen eye for detail and a love for nature — he preferred realistic portraits of people, birds, and animals over large storytelling manuscripts.

    Tip:

    • Akbar = large illustrated manuscripts.
    • Jahangir = individual portraits and albums.
    • Shah Jahan = architecture (Taj Mahal).

    Ancient and Medieval Indian History

    With reference to Mian Tansen, which one of the following statements is not correct?

    1. ATansen was the title given to him by Emperor Akbar.
    2. BTansen composed Dhrupada on Hindu gods and goddesses.
    3. CTansen composed songs on his patrons.
    4. DTansen invented many Ragas.
    Show answer

    Answer: (A) Tansen was the title given to him by Emperor Akbar.

    The correct answer is (A) — this is the INCORRECT statement.

    The title 'Tansen' was given to him by Raja Vikramjit of Gwalior, NOT by Emperor Akbar.

    Akbar gave him the title 'Mian'.

    All other statements are correct:

    • Tansen did compose Dhrupad songs on Hindu gods (B)
    • he composed songs praising his patrons (C)
    • and he is credited with inventing several ragas (D).

    Tip:

    Tansen = title from Gwalior's king.

    Mian = title from Akbar.

    Don't mix up who gave which title!

    Ancient and Medieval Indian History

    With reference to Mughal India, what is/are the difference/differences between Jagirdar and Zamindar?

    1. Jagirdars were holders or land assignments in lieu of judicial and police duties, whereas Zamindars were holders of revenue rights without obligation to perform any duty other than revenue collection.
    2. Land assignments to Jagirdars were hereditary and revenue rights or Zamindars were not hereditary.

    Select the correct answer using the code given below.

    1. A1 only
    2. B2 only
    3. CBoth 1 and 2
    4. DNeither 1 nor 2
    Show answer

    Answer: (D) Neither 1 nor 2

    The correct answer is (D) — Neither 1 nor 2.

    Statement 1 is wrong because Jagirdars were NOT in charge of judicial and police duties — they were mansabdars (military officers) who received land (jagirs) instead of cash salary for military service.

    It was actually the Zamindars who performed local judicial and police functions.

    Statement 2 is also wrong because Jagirs were NOT hereditary — they were transferable and could be taken away.

    Zamindars, on the other hand, were hereditary.

    Tip:

    • Jagirdars = military officers with transferable land.
    • Zamindars = hereditary local chiefs with police/judicial roles.

    Consider the following statements:

    1. Saint Nimbarka was a contemporary of Akbar.
    2. Saint Kabir was greatly influenced by Shaikh Ahmad Sirhindi.

    Which of the statements given above is/are correct?

    1. A1 only
    2. B2 only
    3. CBoth 1 and 2
    4. DNeither 1 nor 2
    Show answer

    Answer: (D) Neither 1 nor 2

    The correct answer is (D) — Neither 1 nor 2.

    Statement 1 is wrong because Saint Nimbarka was a contemporary of Ramanuja (11th century), which is about 400-500 years BEFORE Akbar (16th century).

    Statement 2 is wrong because Kabir (15th century) lived BEFORE Shaikh Ahmad Sirhindi (late 16th-17th century).

    Kabir could not have been influenced by someone born after him.

    Tip: Check the timelines!

    • Nimbarka = 11th century (not Akbar's time).
    • Kabir = 15th century,
    • Sirhindi = 17th century — Kabir came first.

    EXCEPT for trade in tea and trade with China, which the Company retained.

    Statement 2 is correct — the Act asserted the sovereignty of the British Crown over Indian territories held by the Company.

    Statement 1 is correct — Gandhi played a key role in ending the indentured labour system, particularly during his time in South Africa.

    Statement 2 is wrong — Gandhi actually SUPPORTED the resolution to recruit Indians for World War I at Lord Chelmsford's War Conference (1918), believing cooperation would help India's cause for self-rule.

    Why are dewdrops not formed on a cloudy night?

    1. AClouds absorb the radiation released from the Earth’s surface.
    2. BClouds reflect back the Earth’s radiation.
    3. CThe Earth’s surface would have low temperature on cloudy nights.
    4. DClouds deflect the blowing wind to ground level.
    Show answer

    Answer: (B) Clouds reflect back the Earth’s radiation.

    The correct answer is (B) — Clouds reflect back the Earth's radiation.

    Dew forms when the ground cools down enough at night for water vapour to condense on surfaces.

    On a clear night, the Earth's heat radiates freely into space, cooling the ground quickly.

    But on a cloudy night, clouds act like a blanket — they reflect the Earth's heat radiation back to the surface, keeping the ground warmer.

    Since the ground doesn't cool enough, dew doesn't form.

    Tip:

    • Clouds = blanket at night.
    • They trap heat → ground stays warm → no dew.

    The correct answer is (A) — 1 and 3 only.

    Among kharif crops, rice has the highest area under cultivation, so statement 1 is correct.

    Cotton covers more area than sugarcane, so statement 3 is also correct.

    Statement 2 is wrong because oilseeds have more area than jowar.

    Statement 4 is wrong because sugarcane area has not shown a steady decline.

    4. Dshines vertically overhead at the Tropic of Capricorn
    Show answer

    Answer: (A) does not set below the horizon at the Arctic Circle

    The correct answer is (A) — the Sun does not set below the horizon at the Arctic Circle.

    June 21st is the Summer Solstice — the longest day in the Northern Hemisphere.

    On this day, the Sun is directly overhead at the Tropic of Cancer (not the Equator or Capricorn).

    The North Pole is tilted maximally toward the Sun, so places at or above the Arctic Circle experience 24 hours of daylight (midnight sun).

    Meanwhile, the Antarctic Circle has 24 hours of darkness.

    Tip:

    • June 21 = Summer Solstice
    • Sun overhead at Tropic of Cancer

    The correct answer is (B) — The major aim of land reforms was providing agricultural land to all the landless.

    After Independence, land reforms aimed to redistribute land from large landholders to landless farmers for more equitable ownership.

    Option A is wrong because initially the ceiling was individual-based in many states, and it was changed to family-based only after 1971.

    Option C is wrong because the reforms actually promoted food crops (not cash crops), leading to the Green Revolution.

    The correct answer is (D).

    The Inter-Creditor Agreement (ICA) was part of 'Project Sashakt', a plan to resolve bad loans (loans that borrowers fail to repay).

    Here's how it works:

    • For bad loans above Rs. 50 crore that involve multiple banks (called consortium lending), the banks sign an ICA allowing the lead bank to prepare a resolution plan within 180 days.
    • If that fails, the case goes to NCLT (a legal tribunal for company disputes).

    Which of the following is issued by registered foreign portfolio investors to overseas investors who want to be part of Indian stock market without registering themselves directly?

    1. ACertificate of Deposits
    2. BCommercial Paper
    3. CPromissory Note
    4. DParticipatory Note
    Show answer

    Answer: (D) Participatory Note

    The correct answer is (D) — Participatory Note.

    Participatory Notes (P-Notes) are instruments issued by registered Foreign Portfolio Investors (FPIs) to overseas investors who want to invest in Indian stock markets without directly registering with SEBI.

    It is like a shortcut — the FPI buys Indian shares and then issues a P-Note to the foreign investor based on those shares.

    The other options — Certificate of Deposit, Commercial Paper, and Promissory Note — are all money market instruments used for short-term borrowing, not stock market access.

    Tip: P-Notes = backdoor entry to Indian stock markets for foreign investors.

    Show answer

    Answer: (D) Neither 1 nor 2

    The correct answer is (D) — Neither 1 nor 2.

    Statement 1 is wrong because most of India's external debt is owed by private entities, not the government.

    • Commercial borrowings (37.1%)
    • NRI deposits (23.9%)

    form the largest chunks.

    Statement 2 is wrong because India's external debt is in multiple currencies — while the US dollar has the biggest share (about 46%), a significant portion is in Indian rupees (25%), SDR, yen, and euro.

    In the context of India, which of the following factors is/are contributor/ contributors to reducing the risk of a currency crisis?

    1. The foreign currency earnings of India’s IT sector
    2. Increasing the government expenditure
    3. Remittances from Indians abroad

    2. B1 and 3 only
    3. C2 only
    4. D1, 2 and 3
    Show answer

    Answer: (B) 1 and 3 only

    The correct answer is (B) — 1 and 3 only.

    A currency crisis happens when a country's currency loses value sharply, often due to low foreign exchange reserves.

    IT sector earnings (statement 1) bring in foreign currency, and remittances from Indians abroad (statement 3) also bring in foreign currency — both boost forex reserves and reduce the risk of a currency crisis.

    However, increasing government expenditure (statement 2) does not directly increase foreign exchange reserves. It may even worsen things by increasing the fiscal deficit.

    Tip: More foreign currency coming in = safer currency. IT exports and NRI remittances bring dollars in.

    Answer: (A) 1 only

    The correct answer is (A) — 1 only.

    Statement 1 is correct — PPP exchange rates are calculated by comparing what the same basket of goods and services costs in different countries.

    For example, if a meal costs Rs. 500 in India and $10 in the US, the PPP rate is Rs. 50 per dollar.

    Statement 2 is wrong — India is the THIRD largest economy in PPP terms (after China and the USA), not the sixth.

    3. CEasing conditions relating to external commercial borrowing
    4. DFollowing an expansionary monetary policy
    Show answer

    Answer: (D) Following an expansionary monetary policy

    The correct answer is (D) — Following an expansionary monetary policy.

    To stop the rupee from falling, the government/RBI would typically:

    • curb unnecessary imports (A)
    • encourage rupee-denominated bonds like Masala Bonds to reduce dollar demand (B)
    • ease external commercial borrowing to bring in more foreign currency (C)

    However, an expansionary monetary policy (increasing money supply, lowering interest rates) would WEAKEN the rupee further because lower interest rates make India less attractive for foreign investors, leading to capital outflow.

    Tip:

    Expansionary policy = more money supply = weaker currency.

    This is the opposite of what you'd do to save the rupee.

    The correct answer is (B) — Price levels vary from State to State.

    The official poverty line represents the minimum income needed to meet basic needs.

    Since the cost of living (prices of food, essentials) differs from state to state, the poverty line is set higher in expensive states and lower in cheaper ones.

    Show answer

    Answer: (B) Increase in the banking habit of the population

    The correct answer is (B) — Increase in the banking habit of the population.

    The money multiplier shows how much the total money supply increases for every rupee of base money.

    When more people use banks (higher banking habit), more money gets deposited, banks can lend more, and those loans become new deposits elsewhere — creating a multiplier effect.

    Increasing CRR (A) or SLR (C) would REDUCE the multiplier because banks must keep more money in reserve.

    Population increase alone (D) doesn't change the multiplier.

    2. B2 and 3 only
    3. C3 only
    4. D1, 2 and 3
    Show answer

    Answer: (B) 2 and 3 only

    The correct answer is (B) — 2 and 3 only.

    Statement 1 is wrong — the Ramsar Convention encourages countries to conserve wetlands, but it does NOT make it mandatory to protect ALL wetlands. Countries choose which wetlands to designate as Ramsar sites.

    Statement 2 is correct — India's Wetlands Rules, 2010 were framed based on the Ramsar Convention's recommendations for wetland conservation.

    Statement 3 is correct — the Rules cover not just the wetlands themselves but also their drainage areas and catchment regions as identified by the relevant authority.

    Tip:

    • Ramsar = encourages conservation (not mandatory for all wetlands).
    • India's Wetland Rules extend to catchment areas too.

    Answer: (D) 1, 2 and 3

    The correct answer is (D) — All three statements are correct.

    Statement 1: Global warming can melt permafrost and warm ocean floors, which could release the methane trapped in hydrate deposits — a dangerous feedback loop.

    Statement 2: Methane hydrate deposits are found in two main locations — under Arctic permafrost and beneath the ocean floor along continental margins.

    Statement 3: Methane in the atmosphere gets converted (oxidized) to CO2 and water within about 10-20 years by reacting with hydroxyl radicals.

    Tip:

    • Methane hydrate = ice-like methane stored underground/underwater.
    • Warming releases it → more warming (vicious cycle).

    Which of the following statements best describes the term 'xerophytes'?

    1. APlants with very small leaves and thick waxy layers
    2. BPlants growing in extremely dry conditions throughout the year
    3. CPlants that grow as epiphytes
    4. DPlants that are found only in tropical rainforests
    Show answer

    Answer: (B) Plants growing in extremely dry conditions throughout the year

    Option (b) is correct:

    Desert plants lose very little water through transpiration.

    The leaves in desert plants are either absent, very small (tiny), or they are present in the shape of spines.

    This helps in reducing the loss of water from the leaves through transpiration.

    Plants growing in extremely dry conditions throughout the year adopt thorns instead of leaves to prevent loss of water.

    Photosynthesis in these plants is usually carried out by the stems.

    The stem is also covered with a thick waxy layer, which helps to retain water.

    Hence, they have hard and waxy leaves as well.

    Xerophytes are plants growing in extremely dry conditions throughout the year.

    For example, plants growing in deserts (psammophytes), on rock (lithophytes), or alpine plants growing above 14000 feet altitude.

    Elimination Technique: Hard and waxy leaves are a well-known feature of desert plants.

    So, statement 1 must be part of the answer.

    It makes answer B.

    Answer: (B) 2 and 3 only

    The correct answer is (B) — 2 and 3 only.

    H-CNG is a blend of hydrogen (about 18%) with CNG.

    Statement 1 is wrong — H-CNG does NOT eliminate carbon monoxide emissions completely; it only reduces them by up to 70%.

    Statement 2 is correct — H-CNG reduces both CO2 and hydrocarbon emissions compared to regular CNG.

    Statement 3 is correct — hydrogen can be blended up to about one-fifth (18-20%) by volume with CNG.

    Statement 4 is wrong — H-CNG is slightly more expensive than CNG (roughly Rs. 43/kg vs Rs. 42/kg).

    Tip: H-CNG = CNG + 18% hydrogen. It REDUCES emissions but doesn't ELIMINATE them. Slightly costlier than CNG.

    Show answer

    Answer: (B) Hepatitis B, unlike Hepatitis C, does not have a vaccine.

    Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV).

    For some people, hepatitis B infection becomes chronic, meaning it lasts more than six months.

    Having chronic hepatitis B increases the risk of developing liver failure, liver cancer, or cirrhosis (a condition that permanently scars the liver).

    Option (a) is correct: HIV (human immunodeficiency virus) is a virus that attacks the body's immune system.

    It can be transmitted via the exchange of a variety of body fluids from infected people, such as blood, breast milk, semen, and vaginal secretions.

    The Hepatitis B virus also spreads through contact with the blood, semen, or other body fluid of a person who has HBV, much like HIV.

    Option (b) is not correct: Different strains of hepatitis exist, including hepatitis A, B, C, and D.

    Hepatitis B and hepatitis C are both viral infections that attack the liver, and they have similar symptoms.

    People can be effectively protected against Hepatitis B through vaccination.

    In fact, India is the largest producer of recombinant hepatitis B vaccine but there is no effective Hepatitis C vaccine till date.

    Option (c) is correct: As per the World Health Organization (WHO), Hepatitis B and C is a leading infectious killer and affects 325 million people worldwide, leading to about 1.4 million deaths a year.

    It is the second major killer infectious disease after tuberculosis, and nine times more people are infected with hepatitis than HIV.

    Option (d) is correct: Signs and symptoms of hepatitis B range from mild to severe.

    • and overuse of antibiotics in livestock farming (statement 3) — antibiotics fed to animals create resistant bacteria that can spread to humans.

    Statement 1 is wrong because genetic predisposition of people does not cause bacteria to become drug-resistant.

    Statement 4 is wrong because having multiple chronic diseases does not directly cause MDR in bacteria.

    Tip: MDR = wrong antibiotic use by humans + antibiotic overuse in animals.

    Consider the following statements: The Reserve Bank of India’s recent directives relating to ‘Storage of Payment System Data’, popularly known as data diktat, command the payment system providers that

    1. they shall ensure that entire data relating to payment systems operated by them are store in a system only in India.
    2. they shall ensure that the systems are owned and operated by public sector enterprises.
    3. they shall submit the consolidated system audit report to the Comptroller and Auditor General of India by the end of the calendar year

    Which of the statements given above is/are correct?

    1. A1 only
    2. B1 and 2 only
    3. C3 only
    4. D1, 2 and 3
    Show answer

    Answer: (A) 1 only

    The correct answer is (A) — 1 only.

    RBI's data localization directive requires all payment system providers to store their entire payment data within India only.

    This is statement 1, and it is correct.

    Statement 2 is wrong — the directive does not say the systems must be owned by public sector enterprises.

    Private companies can operate them too.

    Statement 3 is wrong — the audit report must be submitted to the RBI (not the CAG), and it must be done by CERT-IN empanelled auditors.

    Tip: RBI's 'data diktat' = all payment data must be stored in India, but ownership can be private.

    Correct Answer: 3 only

    The Core Difference: Signature vs. Certificate

    The examiner is testing whether you can tell the difference between a Digital Signature (an action/mathematical tool) and a Digital Certificate (an identity file).


    1. Identifies the certifying authority (Incorrect)

    • The Mistake: A digital signature doesn't identify the authority; a Digital Certificate does.
    • The Truth: Think of a Digital Certificate like a digital passport issued by an official agency (Certifying Authority) to prove who you are.

    2. Proof of identity to access a server (Incorrect)

    • The Mistake: You don't use a signature to log in or access a secure server; you present your Digital Certificate (like showing your ID card at a secure entrance).

    3. Electronic method of signing and ensuring content is unchanged (Correct)

    • The Truth: This is the exact definition of a Digital Signature. It uses cryptography to lock a document. If anyone alters even a single letter after it is signed, the signature instantly breaks, proving the document was tampered with.

    The Simple Parallel

    Concept Everyday Equal What it actually does
    Digital Certificate Your Passport / ID Card Proves your identity to an outside system or server.
    Digital Signature Ink Signature + Wax Seal Locks a document to prove it came from you and hasn't been altered.

    Because Statements 1 and 2 describe a Certificate, only Statement 3 correctly describes a Signature.

    In the context of digital technologies for entertainment, consider the following statements:

    1. In Augmented Reality (AR), a simulated environment is created and the physical world is completely shut out.
    2. In Virtual Reality (VR), images generated from a computer are projected onto real-life objects or surroundings.
    3. AR allows individuals to be present in the world and improves the experience using the camera of smart-phones or PC.
    4. VR closes the world, and transposes an individual, providing complete immersion experience.

    Which of the statements given above is/are correct?

    1. A1 and 2 only
    2. B3 and 4
    3. C1, 2 and 3
    4. D4 only
    Show answer

    Answer: (B) 3 and 4

    The correct answer is (B) — 3 and 4 only.

    The question swaps the definitions of AR and VR in statements 1 and 2.

    AR (Augmented Reality) adds digital content ON TOP of the real world (like Pokemon Go on your phone camera).

    VR (Virtual Reality) creates a completely artificial world and shuts out the physical world (like wearing an Oculus headset).

    So statement 1 describes VR, not AR — making it wrong.

    Statement 2 describes AR, not VR — making it wrong.

    Statements 3 (AR lets you stay in the real world with digital overlays) and 4 (VR immerses you completely) are correct.

    Tip:

    AR = real world + digital overlay.

    VR = completely virtual world.

    With reference to communications technologies, what is/are the difference/differences between LTE (Long-Term Evolution) and VoLTE (Voice over Long-Term Evolution)?

    1. LTE is commonly marketed as 3G and VoLTE is commonly marketed as advanced 3G.
    2. LTE is data-only technology and VoLTE is voice-only technology.

    Select the correct answer using the code given below.

    1. A1 only
    2. B2 only
    3. CBoth 1 and 2
    4. DNeither 1 nor 2
    Show answer

    Answer: (D) Neither 1 nor 2

    The correct answer is (D) — Neither 1 nor 2.

    Statement 1 is wrong because LTE is marketed as 4G (not 3G), and VoLTE is not called 'advanced 3G'.

    Statement 2 is also wrong — LTE handles data only, but VoLTE handles both voice AND data simultaneously (not voice-only).

    In simple terms: with plain LTE, your phone switches to an older 2G/3G network to make calls, so you lose 4G speed during calls. VoLTE solves this by carrying voice calls over the 4G network itself.

    Tip: VoLTE = Voice over LTE, meaning voice rides on top of your 4G connection.

    2. B2 and 3 only
    3. C3 only
    4. D1, 2 and 3
    Show answer

    Answer: (C) 3 only

    The correct answer is (C) — 3 only.

    Statement 1 is wrong — under the Indian Patents Act, plants, animals, seeds, and 'essentially biological processes' for producing them CANNOT be patented.

    So a biological process to create a seed is not patentable.

    Statement 2 is wrong — the Intellectual Property Appellate Board (IPAB) did exist in India (set up in 1958).

    Statement 3 is correct — plant varieties cannot be patented under Indian patent law, though they can be protected under the Plant Variety Protection Act.

    Tip: In India, you cannot patent seeds, plants, or biological processes — but plant varieties get separate protection.

    Answer: (D) 1, 2 and 3

    The correct answer is (D) — 1, 2 and 3.

    Satellites and remote sensing can measure all three.

    • Chlorophyll content in vegetation (statement 1) is measured using NDVI (Normalized Difference Vegetation Index), which detects how green and healthy plants are based on how they reflect light.

    • Greenhouse gas emissions from rice paddies (statement 2) can be estimated by satellites measuring methane and CO2 concentrations in the atmosphere.

    • Land surface temperatures (statement 3) are routinely measured by thermal sensors on satellites.

    Tip: Satellites can 'see' plant health (NDVI), gas emissions (spectral analysis), and surface temperature (thermal sensors).
