The answer is C. Genetic Isolation.

Genetic isolation occurs when there is no genetic exchange between organisms of the population or species. One of the reasons that cause genetic isolation is geographical separation. The reason why some species of koalas are only found in Australia and lemurs in Madagascar is that they cannot mate with other species outside of their geographical boundary.

The answer is C. Good Luck!!
