The correct answer is: A.Allele frequencies remain unchanged.

Explanation:

Under the Hardy-Weinberg equilibrium, one of the key assumptions is that no migration occurs. This means that there is no gene flow between different populations, and the allele frequencies in the population remain stable over time, provided that other conditions (such as random mating, no mutation, no natural selection, and a large population size) are also met.

The other options are incorrect because:

B.Allele frequencies will shift over time: If...
