Professor Assad suggested that a cautious attitude toward sexual encounters has proven to be more reproductively advantageous to women than to men because the birth process is time-consuming. This suggestion best illustrates the logic of a(n) ________ theory of sexual behavior.

A) evolutionary
B) social learning
C) Freudian
D) role

The suggestion made by Professor Assad is based on the concept of natural selection and how it influences sexual behavior. Evolutionary theory suggests that behaviors that lead to greater reproductive success are more likely to be passed down from generation to generation. Therefore, Professor Assad's suggestion aligns with evolutionary theory as it explains the advantages of a cautious attitude towards sexual encounters in females in terms of reproductive success.
