I believe your answer is B :)
I is answer. Don't open link. It is most likeky unsafe.
When the body perspires, it cools itself due to the high specific heat capacity of water. Perspiration produces a cooling effect.
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.
