The correct answer is: A.It has a larger effect because each individual represents a larger fraction of the gene pool.

Explanation:

Genetic drift is the random fluctuation of allele frequencies that is more pronounced in small populations. In small populations, each individual's genetic contribution is a larger proportion of the total gene pool. Because of this, random events can cause significant changes in allele frequencies over generations, which can lead to the loss of alleles or fixation of certain alleles, reducing genetic diversity.
