The paragraph has a mandatory pair (D-B) as B carries further the idea of opening of the cages, which gets introduced in D. (C-A) is another mandatory pair. Statement C compares India's performance on social indicators with that of Asian economies. Statement A further compares India’s performance with that of poor African countries. Only options (c) and (d) have both mandatory pairs. Option (d) gets negated as the paragraph must start with C, which introduces the para. Option (c) aligns all the statements of the paragraph thereby making it coherent.
