Under Sigmund Freud's Psychosexual Development Theory, during the Phallic Stage, when analyzing the psychological concepts of the 'Oedipus Complex' in boys and the 'Electra Complex' in girls, which of the following is the most crucial and decisive defensive and identification process of this stage?

Detailed Explanation of the Phallic Stage and Identification

According to Sigmund Freud's Theory of Psychosexual Development, during the Phallic Stage (approximately ages 3 to 6), children experience a special romantic attachment toward the opposite-sex parent (Oedipus complex in boys, Electra complex in girls).

• Castration Anxiety: Boys experience a fear of punishment or castration from their fathers.
• Resolution through Identification: To resolve this intense psychological conflict and fear, the child unconsciously identifies with the same-sex rival parent (father for boys, mother for girls).
• Development of Super-ego: This crucial process of identification leads to the internalization of parental values and the development of the Super-ego and conscience.

Therefore, Option B is the correct answer.
