Answer: Oedipal; phallic
Step-by-step explanation:
Oedipal complex is a term used by Sigmund Freud in his theory of psychosexual stages of development, which is analogous to boys as Electra to girls to explain a child's feelings of desire for his or her opposite-sex parent. Jealousy and anger toward the other parents develops.
Here ,in the case of Bart,who begins to find his mother Marge sexually attractive competing with his father for possession of his mother, shows Oedipus complex.
It occurs in the phallic stage when a child is about 3_6 years it is normal and necessary that a child overcomes conflicts at this sexual stages to be able to develop healthy sexual behaviors. When not successfully resolved an unhealthy sexual orientation can develop and cause them to choose romantic partners that resemble their opposite-sex parent.
