The correct answer is: C.extremely large population size.

Explanation:

One of the assumptions of Hardy-Weinberg equilibrium is that the population is extremely large. This condition is meant to minimize the effects of genetic drift, which is a random fluctuation of allele frequencies. In small populations, genetic drift has a more pronounced effect, leading to deviations from Hardy-Weinberg equilibrium. If a population is suffering from genetic drift, it means the population is likely not large enough, which directly violates the assumption of having an extremely large population size.
