Research Indicates People Are Most Likely to Select a Mate

Research indicates people are most likely to select a mate from a nearby village or city,or high school or college.Therefore,the Hardy-Weinberg equilibrium does not apply well to human populations because

A) allele frequency changes in one direction are balanced by changes in the opposite direction.
B) there is no directional trend in selection of mates since most individuals marry someone.
C) individuals are not pairing up by chance across the whole population,and therefore mating is not random.
D) we accumulate adaptive traits that improve the population.
