Concept:
- These four parks lie in four clearly different parts of India, so placing each on a rough map of the country settles the matching without any memorised list.
- North, east, west and south each take one park.
Step 1: Place the park that is obviously coastal.
Sunderban means the mangrove delta where the Ganga meets the sea, which can only be
West Bengal in the east. So b takes iv.
Options (A) and (C) pair b with i and ii, so both are out at once.
Step 2: Place the park in the far south.
Periyar is the name of a river of the Western Ghats in the deep south, which places it in
Kerala. So d takes iii.
Option (B) pairs d with iv, so it fails as well.
Step 3: Check the only option still standing.
Option (D) reads a-ii, b-iv, c-i, d-iii. It has to be verified rather than simply accepted.
Step 4: Verify the remaining two pairs.
Corbett lies in the Himalayan foothills of
Uttarakhand in the north, and Sariska lies in the Alwar district of
Rajasthan in the dry west. Both pairings in option (D) are correct.
Final Answer: (D) a-ii, b-iv, c-i, d-iii
