Answer: (A) Arunachal Pradesh

Arunachal Pradesh fits all three clues:

(1) It lies at approximately 27-29°N latitude — the same latitude that passes through northern Rajasthan (Jaisalmer, Bikaner area).

(2) It has over 80% forest cover — one of the highest in India (as per the Forest Survey of India reports).

(3) Over 12% of its forest area is under Protected Area Network (national parks + wildlife sanctuaries).

Assam has lower forest cover, Himachal Pradesh is at different latitudes, and Uttarakhand doesn't meet all three criteria simultaneously.

Answer: Arunachal Pradesh.

Why this was asked

Arunachal Pradesh has over 80% forest cover, making it one of India's most forested states along with Mizoram and Manipur.

The latitude clue is key - northern Rajasthan (around Jaisalmer-Bikaner) lies at 27-29°N, the same latitude band as Arunachal Pradesh, while Himachal and Uttarakhand are at different latitudes.

UPSC is testing whether students can connect physical geography (latitude) with forest statistics and protected area data - not just memorize state facts in isolation.

Arunachal Pradesh: Location, Forest Cover & Protected Areas

Must know

Located at 27-29°N latitude — same as northern Rajasthan

Highest forest cover in India at over 80%

Over 12% of forest area under Protected Area Network

Good to know

Capital: Itanagar; borders China, Myanmar, Bhutan

Why This Matters

Arunachal Pradesh is India's most forested state and a biodiversity hotspot in the Eastern Himalayas. Its unique latitude position connects it geographically with Rajasthan's northern districts, making it a favorite UPSC trap question.

Forest & Biodiversity

Part of Indo-Burma biodiversity hotspot — global conservation priority

Home to Namdapha National Park — only park with four big cats

Pakke Tiger Reserve and Eaglenest Wildlife Sanctuary are key protected areas

Dense tropical and subtropical forests due to high rainfall from monsoons

Exam traps

Trap: Confusing Arunachal Pradesh with Assam — Assam has lower forest cover

Trap: Thinking Himachal Pradesh fits — it's at different latitude (30-33°N)

Trap: Uttarakhand seems forested but doesn't meet all three criteria simultaneously

Remember: 27-29°N latitude is the key geographic clue that eliminates other options

Why Northeast Dominates

High rainfall from southwest and northeast monsoons creates dense forests

Mountainous terrain with limited agriculture allows forest preservation

Tribal communities have traditional forest conservation practices

Lower population density reduces deforestation pressure compared to plains

Exam traps

Don't confuse forest cover percentage with total forest area — MP leads in area, AP in percentage

Assam has significant forest but much lower percentage due to agriculture and tea gardens

Western Ghats states like Karnataka have good forest cover but not >80%

Exam traps

Don't confuse Tropic of Cancer (23.5°N) with the 27-28°N line mentioned in this question

Northern Rajasthan refers to districts like Bikaner, Jaisalmer — not the Tropic of Cancer line

Latitude determines climate zones — same latitude means similar seasonal patterns despite different geography
