Karen Has Twin 2-Year-Olds, Abe and Ann

Karen has twin 2-year-olds, Abe and Ann. Once her husband played a trick on her and dressed the children in each other's clothes. Karen didn't notice at first, and was "caught" talking more soothingly and attentively to Abe in Ann's clothing than to Ann in Abe's clothing. When the joke was revealed, Karen realized:

A) she, like most parents, had been previously unaware of her differential treatment of the children based on gender.
B) she should get the children to a therapist quickly because of the potential damage done by this change in behavior.
C) she should be sure to get a tea set for Abe and a toy fire truck for Ann to offset any parental influence on their gender roles.
D) she should utilize psychoanalytic methods to understand her behavior.
