Answer:
the conversion of radiant energy into "hidden" form through the process of evaporation.
Explanation:
Latent heat is the heat which is stored in the molecular motion of any substance when it changes its state, Like from solid to liquid, solid to gas or liquid to gas. It is also known as hidden heat.
Example: when water changes its state from water to water vapor, water absorbs energy from the environment. This energy is stored in the molecular movement of water molecules.
On earth, latent heat is transferred when there is evaporation of water from moist land surface or any water body. This causes transfer of heat from earth surface to atmosphere.
Bases on the above definition of latent heat option B is the correct one.
