Answer is D. A new species forms because a group cannot mate with original members of a species.

Geographic isolation refers to a situation where a physical barrier such as a river or a mountain divides a population of species into two or more groups allowing each group to diverge along separate evolutionary paths. Geographic isolation can also result to reducing the flow of genes as the separated groups of animals cannot mate and exchange DNA.
