Given below are four statements (A-D) each with onw or two blanks. Select the the option which correctly fills up the blanks in two statements:
(A) Wimgs of butterfly and birds look alike and are the results of `ul(i)`, evolution.
(B) Miller showed that `CH_(4), H_(2), NH_(3)` and `ul(i)`, when exposed to electric discharge in a flask resulted in formation of `ul(ii)`.
(C) Vermiform appendix is a `ul(i)` organ and an `ul(ii)` evidence of evolution.
(D) According to Darwin evolution took place due to `ul(i)` and `ul(ii)` of the fittest.

Options

A. (D)-(i) Small variations, (ii) Survival (A)-(i) Convergent
B. (A)-(i) Convergent, (B)-(i)Oxygen, (ii) nucleosides
C. (B)-(i) Water vapour, (ii) Amino acids (C)-(i) Rudimentary, (ii) Anatomical
D. (C)-(i) Vestigeal, (ii) Anatomical (D)-(i) Mutations, (ii) Multiplication

Answer

A
