Explanation:

Evaporation is the process of liquid turning to gas. Humidity is the amount of water vapor in the air. When humidity increases, the air has more water vapor, so there's less space for more water to evaporate from a liquid surface. This means the rate of evaporation slows down. Option A is wrong as more humidity doesn't speed it up. Option C is incorrect because the body can still sweat in humidity, but sweat doesn't evaporate easily. Option D is wrong as humidity doesn't double evaporation rate.

Answer:

B. It slows down the rate of evaporation.
