Solution
The correct option is B heat is released
We know that energy (heat) is given to the water, to convert it into vapour (called vaporisation). It means vapour has more energy than water. In the formation of rain, the reverse process takes place (called condensation), therefore vapour releases the heat to convert itself into water.
