B Correct answer
Explanation

Genetic drift causes random changes in allele frequencies from one generation to the next. These changes affect the gene pool of the offspring generation (next generation) as alleles are randomly sampled from the parental gene pool. Over multiple generations, drift can lead to fixation or loss of alleles, particularly in small populations where sampling error is most pronounced.
