Solution

The correct option is A Hypothalamus
The principal heat-regulating centre is located in the hypothalamus, a portion of the fore-brain. This part acts like a thermostat. When the body tends to cool down below the normal temperature, it switches on and speeds up the heat producing process and when the body gets overheated, it accelerates the cooling process and switches off the heat producing processes.
