Answer:
B. polyphyletic group
Explanation:
Polyphyletic group is a taxon which comprises of organisms which are unrelated and do not share a recent or immediate common ancestor. Polyphyletic group is often used to refer to a group of organisms with similar characteristics called homoplasies, but not inherited from a common ancestor.
