The correct answer is: B.a large population that doesn't have genetic drift.

Explanation:

When a population is in genetic equilibrium, it means that the allele frequencies in the population remain constant over time, assuming no evolutionary forces are at work. For this to occur, there must be no genetic drift, no natural selection, no mutation, no gene flow, and random mating. This is most likely in a large population, where the effects of genetic drift (random changes in allel...
