Question
Assertion :It takes longer to dry wet clothes in humid weather. Reason: The presence of humidity in the atmosphere that means water vapour in the atmosphere is already heavy so when we try to dry clothes the evaporation process is slow but effective due to the presence of water vapour in the air.

Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Humidity is the amount of water present in the air. The air around us
cannot hold more amount of water vapor at a given temperature. If the
amount of water in the air is already high.Then the rate of evaporation
decreases.
Now on a humid day , the air already has sufficient
amount of water vapor present . As the result the rate of evaporation
decreases and hence it takes long to dry wet clothes in humid weather.
