According to freud what part of the mind is concerned with morals and ethics?
a. ego
b. preconscious
c. id
d. superego

   D. Superego

Explanation:  While the ID part, according to Freud, represents selfish self, requires the satisfaction of needs, the ego is the part that is more realistic than the ID, still showing a tendency towards satisfying needs, but in a realistic way, looking for a suitable opportunity for such a thing.

The superego is the moral part, which usually represents our awareness of what is good, therefore moral, ethical and what is not.

The preconscious refers to our thoughts which are in the region of the unconscious but are not suppressed, so they can pass into the conscious part of our self.
