Answer:
The correct answer is option B, that is, allopatric speciation.
Explanation:
In allopatric speciation, a species get differentiated into two groups, and each group thrives in isolation of another group. This might take place due to any physical obstruction like a waterway, mountain range, or others that make interbreeding among the two groups impossible.
Due to this each of the separated species evolve distinctly as per the requirement of the habitat and their genetic and physical features.
