The correct option is C Bottleneck phenomenon
Genetic drift is also known as bottleneck phenomenon or Sewall Wright effect. Genetic drift causes a sudden change/loss of gene pool of a species. Due to this the variation of that species reduces which in turn causes reduced genetic diversity in resulting offspring.
