None of the above
Explanation: 

Detailed explanation-1: -If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level. Once the body temperature is back to the correct level, sweating will stop.

Detailed explanation-2: -Body temperature control is a negative feedback system that occurs in the body. If the body temperature rises or falls, the response of shivering or sweating will reverse the change that has occurred.

Detailed explanation-3: -A typical example of a negative feedback mechanism in the human body is the regulation of body temperature via endotherms. When the body’s temperature rises above normal, the brain sends signals to various organs, including the skin, to release heat in the form of sweat.
