Answer 1

The correct option is B it evaporates water from our body

We feel comfortable in fan because it evaporates water from our body.

We get perspiration or sweating because our body tries to cool ourselves by releasing (water) sweat through the pores of our skin. And how when we sit under a fan, the sweat of our body evaporates, due to directed air upon us, making our body cool.
