Why is it harder for evaporation to occur when the air pressure is high? A) Evaporation only occurs when there is no air pressure.
B) The air particles are heavier with little ability to rise.
C) The air particles are packed together with little space for water vapor.
D) The air particles are spread out with plenty of empty spaces for water vapor

(B)The air particles are heavier with little ability to rise.    

Explanation:

Air pressure also affects evaporation. If air pressure is high on the surface of a body of water, then the water will not evaporate easily. The pressure pushing down on the water makes it difficult for water to escape into the atmosphere as vapor. ... Temperature, of course, affects how quickly evaporation happens

and after water is usually warmed by the sun the water temperature raises and then evaporates .
