Answer

Brief Explanations:

Evaporation is a cooling process. When water vapor escapes from a liquid, it takes heat energy with it. Cup A has a lid, so water vapor won't be able to escape easily, reducing the cooling effect due to evaporation. Cup B has no lid, allowing water vapor to escape more freely and thus cooling faster.

Answer:

A. Water vapor won't be able to escape from cup A.
