D. Small population size

Hardy-Weinberg equilibrium requires the presence of a large randomly mating population. Small population size makes the population more likely to deviate from the Hardy-Weinberg equilibrium due to sampling error or chance events occurring during the genetic drift. Large population size ensures that the population maintains the constant allele frequencies over generations, that is the Hardy-Weinberg equilibrium.
