D. Hypothalamus

Answer 1

Hint: It is also known as the Master switchboard of our body. It also maintains the endocrine system of our body.

Complete answer:
The centers that control appetite and feeding behavior are located in the hypothalamus of the brain. To be specific, the ventral posterior nucleus holds the satiety center while the lateral hypothalamic area of the hypothalamus bears the feeding center.
Appealing foods can stimulate appetite even when hunger is not present. Satiety is defined as the feeling of fullness and the suppression of hunger for a period of time, after the meal intake. The feeling of satiety is due to a number of bodily signals that begin when a food or drink is consumed and continues as it enters the gut and is finally digested and absorbed.

Additional Information: The two most important hormones involved in the regulation of hunger and satiety are ghrelin and leptin. The stomach secretes ghrelin when the body requires caloric energy while leptin is produced by our fat cells. It’s considered as the ‘satiety hormone’. It reduces appetite and makes one feel full. As a signaling hormone, their role is to communicate with the hypothalamus that regulates appetite and satiety center.
So, the correct answer is ‘Hypothalamus'.

Note: Appetite exists in all higher life-forms and it serves to regulate adequate energy intake so as to maintain the metabolic needs in the organism. When stressed, appetite levels may increase, and that results in increased food intake. Anorexia refers to the absence of the desire to eat or appetite whereas Polyphagia refers to the increased appetite.
