Detailed explanation-1: -Occurrence of natural selection and small size in population do not meet the criteria for a population to reach Hardy-Weinberg equilibrium. This is because, if the population is undergoing natural selection at the locus under consideration, allele frequencies change continuously in a specific direction.
Detailed explanation-2: -So, the correct answer is ‘The population is small’
Detailed explanation-3: -In order for a population to be in Hardy-Weinberg equilibrium, evolutionary forces such as gene flow, mutation, natural selection, genetic drift, and so on should not be present, and evolution should not occur in the population.
Detailed explanation-4: -There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.
