Evidence suggests that the crocodiles are more closely related to the birds than the turtles and snakes. If so, then including crocodiles, but not birds, in the Class Reptilia would make the Class ReptiliaA. a paraphyletic group.
B. a polyphyletic group.
C. a monophyletic group.
D. parsimonious.
E. not homologous.

The correct answer is - option A.

Explanation:

A paraphyletic group is a group of organism that include only some of descendant of an ancestor. When there is group of organism that are not come from different common ancestor and are unrelated.

A monophyletic is a group of organisms of all the descendants of a common ancestor. In the given case the crocodile, reptiles, and turtles are present in class Reptillia even though crocodile is more closely related to birds. It is belong to the paraphyletic group.

Thus, the correct answer is - option A.

but there is no
