Solution

The correct option is A Forelimbs of man and wings of bird
Human and birds both are vertebrates and forelimb of human has a structural plan similar to birds. Insects are clearly invertebrates and have a different structural plan for their wings. Vermiform appendix and nictitating membrane are both vestigial organs. Archaeopteryx was a primitive reptile that could fly. Only fossils of Archaeopteryx are available and Balanoglossus is a marine worm. Clearly, these are unrelated.
