   B) False

Explanation:  Freud argued that individual's well-being depends on the balance or healthy interaction between ID and the superego, and the ego is responsible for that balance.

ID is an unconscious part of the psyche that seeks to satisfy basic needs, urges, desires, and in this it does not want any compromise, that is, striving for immediate satisfaction of needs. desires and instincts.

Superego, on the other hand, is part of a personality that strives for ideals, morality, and this part of the personality even strives to "make" the ego behave morally, not realistically, as the ego otherwise is.

The ego is precisely that realistic part of the psyche that connects, i.e maintains the balance between Id and superego, because both basic needs and ideals are the reality of the overall psyche of an individual. The ego acts on the principle of reality, not exaggeration to any extreme, and therefore seeks a balance between the two ends, ID and superego, mediating between the basic desires and ideals.
