Explanation:

- According to Sigmund Freud's psychoanalytic theory, the personality is composed of three elements: the id, ego, and superego.

- Id (Option 1): This part represents the primal, instinctual desires and operates based on the pleasure principle, seeking immediate gratification.

- Ego (Option 2): The ego functions as the rational mediator, balancing the impulsive demands of the id with the moral constraints of the superego. It operates on the reality principle and helps the individual navigate societal expectations.

- Correct Answer: Ego

- Superego (Option 3): This aspect embodies internalized societal norms and morals often instilled by parental or cultural influences, striving for perfection and righteousness.

- None of the above (Option 4): This option is incorrect as both ego and superego are part of Freud's model.
