Consider the following Wildlife Sanctuaries of India: 1. Shikari Devi 2. Bhadra 3. Simlipal 4. Pachmarhi Which one of the following is the correct order of the above Wildlife Sanctuaries in terms of their location from south to north?

  1. A.1-2-3-4
  2. B.2-4-3-1
  3. C.2-3-4-1
  4. D.3-1-2-4

Correct answer

C. 2-3-4-1

Explanation

The correct answer is C, 2-3-4-1. From south to north the order is Bhadra (Karnataka), Simlipal (Odisha), Pachmarhi (Madhya Pradesh) and Shikari Devi (Himachal Pradesh).

Bhadra lies in the Western Ghats of Chikkamagaluru district, Karnataka, at about 13.5°N, and is a tiger reserve. Simlipal, in Mayurbhanj district of northern Odisha, lies at roughly 21.5–22°N and is known for its tigers and waterfalls. Pachmarhi, in the Satpura range of Madhya Pradesh, lies a little further north at about 22.5°N and is part of the Pachmarhi Biosphere Reserve. Shikari Devi, in Mandi district of Himachal Pradesh, lies at about 31.5°N, by far the northernmost.

A is wrong because it begins with Shikari Devi, the northernmost of the four.

B is wrong because it puts Pachmarhi south of Simlipal, though Pachmarhi lies slightly further north.

D is wrong because it places Simlipal first and Shikari Devi second, mixing the order.

Exam tip: for such questions place each sanctuary in its state first; the close pair here is Simlipal (about 21.8°N) and Pachmarhi (about 22.5°N).
