Final answer:
In Freudian theory, the Oedipus complex refers to a preschool boy's attraction to his mother and feelings of rivalry with his father. The Oedipus complex is resolved when the boy identifies with his father.
Step-by-step explanation:
In Freudian theory, the correct answer is the Oedipus complex. In the phallic stage of psychosexual development (3-6 years), a preschool boy feels attraction towards his mother and rivalry with his father. This conflict arises from the boy's desire for the opposite-sex parent and jealousy towards the same-sex parent. The boy experiences castration anxiety and the Oedipus complex is resolved when he begins to identify with his father. Failure to resolve the Oedipus complex may lead to fixation and a personality described as vain and overly ambitious.
