UPSC Prelims 2014— Question 26

Correct answer: Option A. Harike Wetland is located at the confluence of the Beas and Sutlej in Punjab. Keoladeo Ghana is not at the confluence of the Banas and Chambal, and Kolleru is a freshwater lake between the Krishna and Godavari deltas rather than the stated Musi-Krishna confluence. Therefore only pair 1 is correct. Option A: Correct. This option is consistent with the governing fact or the valid combination identified in the question. The option reads: “1 only” Option B: Incorrect. This option does not match the verified answer because its proposition, location, institution, sequence, or combination conflicts with the relevant fact tested in the question. The option reads: “2 and 3 only” Option C: Incorrect. This option does not match the verified answer because its proposition, location, institution, sequence, or combination conflicts with the relevant fact tested in the question. The option reads: “1 and 3 only” Option D: Incorrect. This option does not match the verified answer because its proposition, location, institution, sequence, or combination conflicts with the relevant fact tested in the question. The option reads: “1, 2 and 3” The key Prelims lesson is to test each proposition independently before selecting the combination. Where the question uses words such as 'only', 'all', 'none', 'always' or a precise institutional/geographical association, a single inaccurate component is sufficient to eliminate the option. The answer recorded here follows the official answer key for the question-paper series represented by the uploaded source and has been cross-checked against an independent published key.
