If a person does not eat for a period of time, it causes a need for food. This need produces a state of tension. The tension energizes the person to act in some way to find food, thereby returning the body to homeostasis. This is an example of: a Intrinsic action pattern b Sympathetic nervous system c Extrinsic motivation d Drive reduction theory e Biological needs

d. Drive reduction theory

Explanation:

Drive reduction theory is the theory that draws the attention towards the reason that how the motivations are originated from the biological needs. Clark Hull was the behaviorist who proposed the Drive reduction theory. he defined the origination of motivation to be born out of the biological or physiological needs of the body. The state of tension is created in the mind that further escalates the need to reduce the need.  

In the given situation, the example of Drive reduction theory has been stated. The drive of hunger gives rise to find the food and have it.
