The following lists I and II show the names of Economists/Authors and their books respectively. Match List-I with List-II and choose the correct answer using the codes given below the lists:List I · Economist/AuthorList II · BookA. Myrdal1. Economic Theory and Under-developed RegionsB.

The Wealth of NationsThe following lists I and II show the names of Economists/Authors and their books respectively. Match List-I with List-II and choose the correct answer using the codes given below the lists:

1. A

   1 2 3 4

   Option (a) pairs Myrdal with Economic Theory and Under-developed Regions, Hirschman with The Strategy of Economic Development, Kaldor with Strategic Factors in Economic Development, and Adam Smith with The Wealth of Nations, matching A-1, B-2, C-3, and D-4 respectively. This direct alignment represents the exact author-book pairing established in economic literature. Because all four classic works are correctly attributed to their respective economists without any transposition, this is the designated key.

2. B

   2 3 1 4

   Option (b) incorrectly pairs Myrdal with The Strategy of Economic Development instead of his actual work on under-developed regions. It misaligns the sequence by mixing up the contributions of Hirschman and Kaldor. Therefore, this option is incorrect.

3. C

   3 2 1 4

   Option (c) starts by attributing Strategic Factors in Economic Development to Myrdal, which is factually inaccurate. Such a transposition disrupts the entire matching sequence of the lists. Hence, this option is rejected.

4. D

   2 1 3 4

   Option (d) assigns Hirschman's work to Myrdal and places Kaldor incorrectly, failing to yield the accurate code combination. Consequently, this option cannot be accepted as the right answer.

Summary. Official key is (a) matching the authors to their respective seminal economic texts accurately. Gunnar Myrdal wrote Economic Theory and Under-developed Regions, while Albert Hirschman authored The Strategy of Economic Development. Nicholas Kaldor contributed Strategic Factors in Economic Development, and Adam Smith famously wrote The Wealth of Nations. Aspirants often confuse the specific books written by development economists like Myrdal and Hirschman. Carefully verifying each economist with their recognized publication ensures the correct code is selected.
