Answer:
The correct option is : D) latent heat
Explanation:
The latent heat is described as the hidden thermal energy absorbed or released by a system or a body, in a constant-temperature process.
It is the amount of heat transferred during a process, without changing the temperature of the body.
It is also defined as the heat associated with the change of phase of a substance. Example: freezing, melting, vaporization or condensation.
Therefore, release of stored heat energy when water freezes is called the latent heat.
