C Correct answer
Explanation

Perspiration (sweating) is the body's primary cooling mechanism. When sweat evaporates from the skin surface, it absorbs heat energy from the body, lowering temperature. Respiration is for gas exchange, meditation is mental practice, and mastication is chewing - none of these directly cool the body. This is why we sweat during exercise or in hot environments.
