Assertion :We wear cotton clothes in summer. Reason: The mechanism of our body to keep us cool, during evapourisation the particles at the surface of the liquid gain energy from the surroundings or body surface and change into vapour. The heat energy equal to the latent heat of vapourisation is absorbed from the body leaving the body cool.

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
During summer, we perspire more because of mechanism of our body which keeps us cool. Cotton clothes being a good absorber of water helps in absorbing the sweat and exposing it to the atmosphere for easy evaporation.
Hence, we wear cotton cloths during summer.
