1. A

   2 1 3 4

   Option (a) incorrectly pairs Manas with Uttar Pradesh, Sundarbans with Madhya Pradesh, Nanda Devi with Assam, and Pachmarhi with West Bengal. These state assignments completely mismatch the actual geographical locations of the biosphere reserves. Therefore, this sequence is entirely incorrect.

2. B

   4 3 2 1

   Option (b) pairs Manas with West Bengal, Sundarbans with Assam, Nanda Devi with Uttar Pradesh, and Pachmarhi with Madhya Pradesh. While some individual pairings might appear plausible, the sequence fails to correctly align every bio-reserve sector with its designated state. Hence, this option is ruled out.

3. C

   1 2 3 4

   Option (c) associates Manas with Madhya Pradesh, Sundarbans with Uttar Pradesh, Nanda Devi with Assam, and Pachmarhi with West Bengal. This ordering is arbitrary and contradicts the established administrative and ecological map of India's biosphere reserves. Thus, it is the wrong choice.

4. D

   3 4 2 1

   Option (d) correctly matches Manas with Assam (3), Sundarbans with West Bengal (4), Nanda Devi with Uttar Pradesh or Uttarakhand region historically listed here (2), and Pachmarhi with Madhya Pradesh (1), yielding the code 3 4 2 1. Manas is globally renowned for its wildlife in Assam, Sundarbans spans the delta in West Bengal, Nanda Devi is anchored in the northern mountainous tract, and Pachmarhi sits centrally in Madhya Pradesh. This precise cross-referencing of all four items accurately establishes the correct matching sequence as per official data.

Summary. Official key is (d) matching List-I bio-reserves with their correct Indian states in List-II. Manas is located in Assam, Sundarbans in West Bengal, Nanda Devi in the northern region, and Pachmarhi in Madhya Pradesh. Candidates must carefully trace each reserve to its respective state to avoid confusion among similar names. Option (d) provides the accurate numerical code 3 4 2 1 for these pairings. Thus, all other combinations fail to establish the correct geographical correspondence.
