Social Research Indicates That a Person Is Most Likely to Marry

Social research indicates that a person is most likely to marry someone from the same village or city,or a high school or college classmate.Therefore,the Hardy-Weinberg equilibrium does not apply well to human populations because

A) allelic 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 genetic drift is more likely to change gene frequencies.
D) this increases gene flow.
E) we accumulate adaptive traits that improve the population.
