According to Sigmund Freud, which component of personality develops first?

The correct answer is the Id, as it represents the most primitive part of the personality structure according to Sigmund Freud's theory. The Id is present from birth and operates on the pleasure principle, seeking instant gratification of basic urges, needs, and desires without considering reality or social norms. It is entirely unconscious and drives our most basic instincts, such as hunger, thirst, and sex.

Freud proposed that as a child grows and interacts with the world, other components of personality, such as the Ego and the Superego, develop. The Ego, which develops next, is responsible for dealing with reality and mediates the desires of the Id with the constraints of the external world. The Superego, which represents internalized moral standards and societal rules, is the last to develop. Therefore, the Id is fundamental and develops first in Freud's model of personality.
