Correct answer: A

Evaporation is escape of the fastest particles from the surface, and it goes on at all temperatures below boiling.
It is faster with more surface area, higher temperature and wind, and slower in humid air. It cools the liquid left behind.

Worth noting

Clothes dry slowly on a humid monsoon day because the air already holds a lot of water vapour.
