The correct answer is: A.Allopatric Speciation

Explanation:

In this case, the raft of Amazon ants is carried away by a flash flood, leading to the physical separation of the two populations. Since there is enough distance between them and they will never meet again, this physical isolation prevents gene flow between the two groups. Over time, these isolated populations may evolve into distinct species due to differences in their environments or other factors. This is an example of allopatric speciation, where geographic isolation causes the populations to evolve separately.

A.Allopatric speciation occurs when populations are geographically separated, leading to ...
