Solution
The property of water that is directly responsible for lowering body heat with sweat is (Choice A) Heat of Vaporization. This is because when sweat (which is mostly water) evaporates from the surface of your skin, it takes with it a large amount of heat, thus cooling your body down. This process utilizes water's high heat of vaporization.
