Answer : Option C
Explanation :
A fan produces a feeling of comfort because our perspiration or sweating evaporates rapidly. Our body tries to cool ourselves by releasing sweat through pores of our skin. And when we sit under the fan, the sweat of our body evaporates due to directed air upon us making our body cool.
