Answer:

A. Populations were separated through geographical isolation.

Explanation:

The given case of deer mice is an illustration of the separation of populations via geographical isolation.

What is geographical isolation?

The phenomenon in which two populations get separated due to geographical barriers like mountains, rivers, or any kind of water body is termed as geographical isolation.

It is a key element in allopatric speciation. If the flow of the gene get interrupted for prolonged time due to geographical barriers, the separated populations get evolve independently and ultimately result in different species.

Thus, the given case of deer mice in Michigan which got separated by large glacial lake resulted in two different populations due to geographical isolation.
