The correct option is this: WATER GAINS ENERGY FROM SUNLIGHT AND IS CONVERTED TO VAPOUR.

When heat is applied to a sample of water, the molecules of water will gain kinetic energy and move about with more energy. As the energy increases, the kinetic energy and the motion of the water molecules also increase. When a particular temperature is reached, the energy acquired by the water molecules will be used to break the bonds that hold the water molecules together and the molecules will escape into the atmosphere as steam. In the question given above, the water molecules gains energy from sunlight, the inter molecular forces between them was broken and they escape into the atmosphere in form of vapour.
