Correct Answer: Both I and II


Solution : The correct answer is Both I and II.

I. An increase in surface area: The larger the surface area, the more molecules can escape into the air, leading to an increased rate of evaporation.

II. A decrease in humidity: Humidity refers to the amount of moisture in the air. When humidity is lower, the air can hold more water vapour, creating a concentration gradient that promotes faster evaporation.

Therefore, both an increase in surface area and a decrease in humidity contribute to an increased rate of evaporation.
