Explanation:

Freud's theory of the personality explains the role of the id, ego and superego as follows:

Id: is responsible for instinct and urges. It’s sole goal is to achieve instant satisfaction.

Ego: helps distinguish reality from the impossible. It kind of fine tunes the id to be more compliant with the real world, as well as making the personality acceptable to society.

Superego: is the internal moral judge, it is responsible for how a person determines what is wrong or right.
