Monogamy Is the Primary Form of Marriage in Most Agricultural

Monogamy is the primary form of marriage in most agricultural states. The probable reason this pattern is so prevalent is:

A) Most agricultural states have laws against polygamous marriages of any kind because they disrupt the normal flow of the agricultural cycle.
B) In agricultural societies, where land is a scarce commodity, peasants cannot afford the luxury of polygyny.
C) Polygyny is impossible because there are fewer women than men in agricultural states.
D) Most peasants can only afford to accumulate enough wealth for one dowry.
