None of the above

Detailed explanation-1: -Bat wings and whale fins are a good example this. While they don’t appear similar from the outside and function differently, the skeletal structure of these two features are actually very similar, as they are rooted in a common ancestor. Most hands, wings and flippers in mammals are homologous.
Detailed explanation-2: -This is known as homologous structure. human arms, cat forelegs, whale flippers, and bat wings all have the same basic bone structure. While the function of each of these is different, they are all variations of a common ancestor, that has simply adapted to different functions.
Detailed explanation-3: -So, the correct option is ‘Homologous organs’.
Detailed explanation-4: -Homologous structures are similar physical features in organisms that share a common ancestor, but the features serve completely different functions. An example of homologous structures are the limbs of humans, cats, whales, and bats.
