According to Freud,boys in the third psychoanalytic stage of development:

A) are openly angry with their fathers.
B) secretly want to replace their fathers.
C) disrespect their mothers.
D) believe their fathers are perfect.

According to Freud's psychosexual theory of development, boys in the third stage (phallic stage) experience the Oedipus complex, in which they desire their mothers and feel jealous of their fathers. This conflict is resolved when they identify with their fathers and adopt societal norms and values. Therefore, they secretly want to replace their fathers rather than openly being angry with them.
