Correct answer: (b) 2 1 4 3
Explanation
- A
1 2 4 3
Option (a) pairs D. K. Karve with establishment of a girls school, which is incorrect because Karve is properly linked to the Widow Re-marriage Association.
- B
2 1 4 3
Option (b) correctly matches D. K. Karve with Secretary of the Widow Re-marriage Association, J. E. Bethune with the establishment of a girls school in Calcutta, Ishwar Chandra Vidyasagar with being Principal of Sanskrit College, and B. M. Malabari with starting a crusade against child marriage. This sequence accurately reflects the historical associations of these social reformers and educators in nineteenth- and early-twentieth-century India, making it the correct option.
- C
2 1 3 4
Option (c) misplaces Ishwar Chandra Vidyasagar and B. M. Malabari by swapping their respective historical contributions, failing the correct code sequence.
- D
1 2 3 4
Option (d) incorrectly aligns D. K. Karve with the Calcutta girls school and alters the remaining proper pairings of the list.
Summary. Official key is (b) because it accurately matches every personality in List-I with their correct historical work or office in List-II. D. K. Karve served as secretary of the Widow Re-marriage Association, while J. E. Bethune established the famous girls school in Calcutta. Ishwar Chandra Vidyasagar notably acted as principal of Sanskrit College, and B. M. Malabari led the crusade against child marriage. This precise alignment yields the code 2, 1, 4, 3. Wrong options fail by swapping these well-documented social reform associations.
