Explanation / Answer

Temperature regulation in our body is monitored by thermoregulation center of hypothalamus. The mechanism is operated by negative feedback mechanism. When, the body temperature is too hot, sweat glands in skin are stimulated to produce sweat and heat is sent out of body cooling the body. During hot conditions, the vasodilation in blood vessels of skin redirect the flow from heart to body core to outside. This increase in blood flow releases heat to outside. Therefore, Option 4 is correct.
