The correct option is C.
Water has many unique properties and one of the properties is its high heat capacity. The specific heat capacity of water refers to the quantity of heat that is needed to raise a unit mass of water by one degree Celsius. A large quantity of heat is required to raise the temperature of water by one degree Celsius, this large capacity for heat makes water to be an effective coolant. Because of its high heat capacity water is able to absorb heat from its surrounding and keep the surrounding cool for a long time.
