What would be the result of physical exertion on the part of a person who has fallen into cold water?

A it will decrease exposure of the body surface to cold water

B it will increase the water temperature between the body and layers of clothing

C it will increase the rate of heat loss from the body

D it will increase survival time in the water

AI Explanation

The correct answer is C) it will increase the rate of heat loss from the body. Physical exertion in cold water leads to increased blood circulation, which brings more warm blood to the skin and increases the rate of heat loss from the body. This accelerates hypothermia and reduces survival time in the water. The other answer choices are incorrect because: A) Physical exertion does not decrease the body's exposure to cold water. B) It does not increase the water temperature between the body and clothing layers. D) Increased heat loss from physical exertion actually decreases survival time in cold water, not increase it.
