The correct answer is B. Sweating
Step-by-step explanation:
Homeostasis involves processes in living organisms that aim at preserving stable internal conditions, this includes temperature regulation, fluids regulation, glucose, and energy levels, among others. Sweating or perspiration is an example of homeostasis because this mechanism allows mammals to regulate their temperature (thermoregulation). Due to this, in hot weather or conditions humans and other mammals sweat which has a cooling effect on the body and therefore, keeps the temperature stable as part of homeostasis.
