- D.(a)-(iii); (b)-(ii); (c)-(i); (d)-(iv)
Correct Answer
(C) (a)-(iv); (b)-(iii); (c)-(ii); (d)-(i)
Solution & Explanation
Answer: (C) (a)-(iv); (b)-(iii); (c)-(ii); (d)-(i). Adaptive radiation is best illustrated by Darwin Finches (iv). Convergent evolution gives analogous structures such as the wings of butterfly and birds (iii). Divergent evolution gives homologous structures such as the bones of forelimbs in Man and Whale (ii). Evolution by anthropogenic action is the selection of resistant varieties due to excessive use of herbicides and pesticides (i). NCERT Reference: Ch 6 Evolution, p.114, lines 6–13: "whales, bats, Cheetah and human (all mammals) share similarities in the pattern of bones of forelimbs... This is divergent evolution and these structures are homologous."
