Answer:

The answer is a) allopatric speciation.

Explanation:

Allopatric speciation happens when a geographical or physical barrier is introduced in a population. After this, the reproductive isolation, genetic recombination and also random mutations can promote the speciation process, where at the end, there will be two separate species.
