Show answer

Answer: (C) 3 and 4

Pair 1 — WRONG:

Cardamom Hills are in Kerala/Tamil Nadu (Western Ghats),

NOT on the Coromandel Coast.

The Coromandel Coast is the eastern coast of South India (Tamil Nadu/Andhra Pradesh).

Pair 2 — WRONG:

Kaimur Hills are in the Vindhyan Range (Bihar/UP/MP — central-eastern India),

NOT on the Konkan Coast.

The Konkan Coast is the western coast of Maharashtra/Goa/Karnataka.

Pair 3 — CORRECT:

Mahadeo Hills (part of the Satpura Range) are in Central India (Madhya Pradesh).

Pachmarhi, India's famous hill station, is in the Mahadeo Hills.

Pair 4 — CORRECT:

Mikir Hills (also called Karbi Anglong Hills) are in North-East India (Assam).

The Karbi Anglong district is named after these hills.

Pairs 3 and 4 are correct.

(Ref: NCERT Class 11)

Why this was asked

Hill ranges define India's regional boundaries and are crucial for understanding the country's physical divisions that appear in multiple UPSC subjects including geography, ecology, and governance.

UPSC tests precise location knowledge by pairing hill ranges with incorrect coastal regions - students often confuse eastern Coromandel Coast with western Cardamom Hills and western Konkan Coast with interior Kaimur Hills.

The question requires memorizing specific hill locations within India's physiographic framework rather than understanding geological processes.
