Homology is defined as structures which are derived from a common ancestor like wings of bird and forelimbs of bat. Divergent evolution: It is the process where two or more related species become more and more dissimilar. Divergent evolution produces homologous structures e.g.same bones can be used in many ways leading to divergent evolutionary paths like frogs, bats, birds so on. So the correct option is (c):Divergent evolution. Solution Homology is defined as structures which are derived from a common ancestor like wings of bird and forelimbs of bat.
