The wings of a bird and those of an insect

Detailed explanation-1: -So the least likely among the rest is the wings of a bird and those.
Detailed explanation-2: -Flippers of whales and wings of birds considered as homologous organs because they both have the same anatomy, i.e., they have same skeletal structures, and they perform different functions. Flippers of whales are used to swim whereas the wings of birds are used for flight.
Detailed explanation-3: -An insect’s wings and the wing of a bird represent convergent evolution but they are not homologous structures. Because the basic anatomy of an insect’s wings differs from that of a bird’s wing, they are analogous to the wings of a bird.
Detailed explanation-4: -So, the correct option is ‘Wings of Grasshopper and forelimbs of Flying Squirrel’.
Detailed explanation-5: -Hence, the wings of butterflies and bats are not the examples of homologous organs.
