Option A
Explanation:
In evolution a number of organisms have lost some of their structures and a number of organisms have gained some of their structures for their survival. According to Darwin , the most fittest organism has survived.
For exhibiting this many organisms have attained several modifications. So when we look into homologous structures in 2 different species we can thereby relate and tell that they are from a common ancestor.
