Answer:
Correct Answer: D
Solution:
In allopatric speciation (species formation), a part of the population becomes geographically isolated from the main population.
The population becomes entirely separated and finally constitutes a new species.
In sympatric speciation, a small segment of the original population becomes reproductively isolated.
As the isolating mechanism comes into force, a new species emerges.
In due course of time, a new species is formed.
