One Current Hypothesis About Why There Are Socioeconomic Differences in Parenting

One current hypothesis about why there are socioeconomic differences in parenting practices is that

A) genetic differences between lower-SES families and higher-SES families enable lower-SES families to cope with difficulties more easily.
B) the increased stress that lower-SES parents experience causes them to have less time and energy for complex child-rearing issues than do higher-SES parents.
C) higher-SES parents are more concerned about protecting their children from harm than are lower-SES parents.
D) the jobs common to higher-SES families require a greater degree of conformity than the jobs common to lower-SES families.
