Hint:
Evaporation: It is a sort of vaporization of a fluid that happens just on the outside of a fluid. The other sort of vaporization is bubbling, which, rather, happens on the whole mass of the liquid.

Complete step by step answer:
The change in liquid to gaseous form is called evaporation. In this process, the mixture is warmed. When the liquid part evaporates and escapes, which leaves behind the solid part.
For example: when a mixture of common salt and water can be separated by evaporation.
Evaporation causes cooling. Since in evaporation, the water changes structure liquid to gaseous state so the vapors of water make the surface cool.
Evaporation causes cooling in light of the fact that during vanishing the molecule of the liquid absorbs vitality from the environmental factors to recover the energy lost during evaporation. The absorption of heat from the surroundings makes the surrounding cool.

Hence, the correct option is A.

Additional Information:
Uses of evaporation:
-Evaporation lakes are utilized to forestall pesticides, composts, and salts from horticultural wastewater from debasing the water bodies they would stream into.
-Evaporation of ocean water to deliver salt.
-In industry, the standards of evaporation and refrigeration are utilized to an extraordinary degree in the treatment, detachment, dealing with, and capacity of materials in any of the three conditions of an issue - Solid, Liquid, or Gas. Refining concerns the detachment of liquid mixtures by evaporation methods.
-It is significant additionally in cooling, refrigeration, and refining. Substances are evaporated in a halfway vacuum to speed vanishing or to forestall decay by heat. Instant espresso and frozen squeezed orange are evaporated along these lines, as are blood plasma, immunizations, and antitoxins, for example, penicillin. Camphor is cleansed by sublimation.

Note:
Evaporation has no such effect on the weight of a liquid. Also, as evaporation increases, the density of a liquid decreases, and vice versa.
