Answer 1

The correct option is B below boiling point

Evaporation is the process in which a liquid gets converted into vapour below its boiling point.
It is a surface phenomenon. The particles on the surface of a water body gain energy to overcome the force of attraction and gets converted to vapours.
For example, wet clothes get dried on a sunny day due to evaporation.
