Answer: A. Drive-reduction theory.
Step-by-step explanation:
According to the drive-reduction theory of motivation, individuals are prompted to meet physiological needs so they can sustain homeostasis.
This theory was first introduced by Clark Hull in 1943. He stated that biological drives serve the purpose of correcting the irregularities in homeostasis. Physiological demands provoke psychological drive states that lead the behavior to meet those needs in order to return the system to homeostasis.
