Final answer:
The answer to the question is 'a) Id.' The id is the part of the personality that seeks immediate gratification, which the superego and ego work together to suppress in order to maintain balance and social conformity.
Step-by-step explanation:
The question is referring to Sigmund Freud's psychoanalytic theory of personality, specifically the interplay between the id, ego, and superego. Freud believed that the id is the part of the personality that contains our most primitive impulses such as hunger, thirst, and sex, and operates on the pleasure principle, seeking immediate gratification. The superego is the moral compass, developed through social interactions, and aims for perfection by judging our behavior.
The ego balances the impulsive demands of the id and the moralistic demands of the superego, usually operating on the reality principle. Therefore, in the context of the question, 'It's Superego & his sidekick, Ego, suppressing this,' the answer is a) Id, as the id is the part of the psyche that is suppressed by the actions of the superego and ego.
