Why can evaporation slow down after it increases the moisture in near-surface air?

Answer and explanation

Correct answer: Because the vapour-pressure gradient decreases

Correct answer: A. Evaporation is driven in part by the difference between the saturation vapour pressure at the water surface and the actual vapour pressure in the air. As evaporation makes nearby air more humid, its vapour pressure rises and this difference can shrink. The weaker gradient can slow evaporation, though wind, temperature, and other conditions also affect the rate.
