Answer
Both A and R are true and R is the correct explanation of A
Explanation
Assertion (A) is true because a humid environment already has a high concentration of water vapour in the air thus, the rate of evaporation becomes slow.
Reason (R) is true because since the air is already saturated with vapour, fewer water molecules from the surface can escape into the air so they don’t find enough space to move into.
Here, reason clearly justifies why the rate of evaporation is slow in humid environment.
