So, when the Hector is running for a long time, the body heats up due to constant retraction and expansion of the muscle due to friction, the glucose molecule as energy is also exhausted, so counter the change, sensory system, cools the body from the heat produced, the cooling of the body is achieved by sweating. Therefore, Option A is the correct answer.
