The correct answer is: C.Speciation

Explanation:

When a population becomes isolated from other populations of the same species and genetic differences begin to accumulate over time, speciation can occur. This is because isolation leads to the development of reproductive barriers (such as genetic, behavioral, or ecological differences), preventing interbreeding even if the populations come into contact again. Eventually, these differences may result in the formation of two distinct species.

The other options are not the primary outcomes in this scenario:
