Answer:
Option A.
Explanation:
Drive , is the right answer.
In psychology, a drive theory is a philosophy that strives to examine, order or determine the psychological drives. It is an instinctual requirement that has the potential of driving the action of a person; an "excitatory event created by a homeostatic disturbance". This is based on the belief that people are born with some psychological obligations and that a contrary position of stress is generated when these needs do not get fulfilled. According to the assumption, drive tends to develop with time and works on a feedback regulator mode, such as a thermostat.
