Answer 2

Explanation:

C.fish and frog is the correct answer.  A cladogram is a pictorial representation which tells about the process of evolution which are reflected in the modern taxonomy. Each branch of the cladogram is called clade and it represents all kinds of changes which eventually lead to the generation of new species. It is believed that if the two species are closer in the cladogram, then it is more likely to share a common ancestor. so here fish and frog would be the right answer.
