The correct answer is: C.founder's effect.

Explanation:

Genetic drift can occur due to two main chance events:

1.Bottleneck effect: This occurs when a population's size is dramatically reduced due to a catastrophic event (such as a disaster), resulting in a loss of genetic diversity.

2.Founder’s effect: This happens when a small group of individuals establishes a new population, and the allele frequencies of that new population may be significantly different from the original population due to the small size...
