Explanation:
The correct answer would be that the nervous system transmits feelings of hunger to the brain, which initiates eating.
<em>The human stomach and intestinal tracts consist of receptors that are able to sense the presence or absence of nutrients and send messages to the brain accordingly. If there are adequate nutrients in the stomach and the intestinal tracts, the receptors send a message to the brain and the hormone that makes humans feel fullness in their stomach is released into the blood. Once the available nutrient is low, the receptors send a message to the brain which in turn releases hormones into the blood that makes humans feel the sensation of hunger. </em>
The correct option is c.
