answer of the question: B
The correct answer is option B, that is, Genetic drift greatly affects small populations, but large populations can recover.

Genetic drift refers to a change in the relative frequency of distinct genotypes in a small populace, owing to the chance vanishing of specific genes as individuals do not reproduce or die.
