The correct answer is: A.Allele frequencies may change, disrupting the equilibrium.

Explanation:

When migration (or gene flow) occurs between two populations, individuals from one population move to another, bringing their alleles with them. This can introduce new alleles or change the frequency of existing alleles in the receiving population. Since the Hardy-Weinberg equilibrium assumes no migration, the introduction of gene flow disrupts this equilibrium by altering allele frequencies.
