The condition that must be met for Hardy-Weinberg equilibrium is:

C.No natural selection - The Hardy-Weinberg equilibrium assumes that there is no natural selection acting on the population. Natural selection would cause certain alleles to become more or less frequent over time, violating the equilibrium.

The other options are incorrect because they violate the Hardy-Weinberg equilibrium conditions:

A.Extremely small population size - Small populations are subject to genetic drift, which is a random change in allele frequencies. Hardy-Weinberg equilibri...
