Correct Answer: A
Solution :
Wings of butterfly and birds look alike and are the result of convergent evolution. Miller showed that \[C{{H}_{4}},{{H}_{2}},N{{H}_{3}}\]and water vapour, when exposed to electric discharge in a flask, resulted in formation of amino acids. Vermiform appendix is a vestigial organ and an anatomical evidence of evolution. According to Darwin, evolution took place due to small variations and survival of the fittest. Hence, option [a] is correct.
