A. Drive-reduction theory.

Explanation:

According to the drive-reduction theory of motivation, individuals are prompted to meet physiological needs so they can sustain homeostasis.

Physiological demands provoke psychological drive states that lead the behavior to meet those needs in order to return the system to homeostasis.
