Assertion: The resolution of the Oedipus complex involves boys giving up their sexual feelings for their mothers and identifying with their fathers.

Reason: Identification with the same-sex parent is a critical component in resolving the Oedipus complex.

Both Assertion and Reason are true, and the Reason is the correct explanation of the Assertion.

Freud's assertion that boys give up their sexual feelings for their mothers and identify with their fathers to resolve the Oedipus complex is true. This process involves accepting the father's relationship with the mother and modeling behavior after the father. The reason given is also true, as identification with the same-sex parent is a critical component in resolving the Oedipus complex for boys. It helps in redirecting sexual desires, resolving conflicts, and establishing appropriate gender identity.
