According to Freud, which personality trait is responsible for generating impulses?

The correct choice is C, the Id. In Freudian theory, the Id is the part of the personality that contains our basic instinctual drives and desires. It operates on the pleasure principle, seeking immediate gratification and the fulfillment of basic needs and desires without considering the realities of the world or moral constraints. The Id is impulsive and operates unconsciously, making it the source of instinctual energy that drives a person’s impulses.

The Id's role is foundational in Freud's model of the psyche, which also includes the Ego and Superego. The Ego serves as a mediator between the Id's desires and the external world's realities, while the Superego embodies the moral standards and ideals we acquire from our parents and society. Because of this structure, the Id is solely responsible for generating those raw impulses, making it the correct answer in this context.
