The Oedipus complex occurs in which stage of Freud's theory of psychosexual development?

Phallic Stage

The correct answer is Option (3) → Phallic Stage

In Freud’s theory of psychosexual development, the Oedipus complex occurs during the phallic stage, which typically takes place between the ages of 3 and 6 years. In this stage, a child develops unconscious sexual desires for the opposite-sex parent and feelings of rivalry toward the same-sex parent.

"Phallic Stage : This stage focuses on the genitals. At around ages four and five children begin to realise the differences between males and females. They become aware of sexuality and the sexual relationship between their parents. During this stage, the male child experiences the Oedipus Complex, which involves love for the mother, hostility towards the father, and the consequent fear of punishment or castration by the father (Oedipus was a Greek king who unknowingly killed his father and then married his mother). A major developmental achievement of this stage is the resolution of the Oedipus complex. This takes place by accepting his father’s relationship with his mother, and modelling his own behaviour after his father. For girls, the Oedipus complex (called the Electra Complex after Electra, a Greek character, who induced her brother to kill their mother) follows a slightly different course. By attaching her love to the father a girl tries to symbolically marry him and raise a family. When she realises that this is unlikely, she begins to identify with her mother and copy her behaviour as a means of getting (or, sharing in) her father’s affection. The critical component in resolving the Oedipus complex is the development of identification with the same sex parents. In other words, boys give up sexual feelings for their mothers and begin to see their fathers as role models rather than as rivals; girls give up their sexual desires for their father and identify with their mother"
