That's a negative, A is the only correct answer.
when air is rising, it expands.
for expansion you need energy
latent energy from the surrounding air is used -> the air cools.
The Relative Humidity is (e/E)100% or (x/X)100%.
both e and x remain the same, however E and X decrease due to the temperature decrease. So the relative humidity increases. When you reach 100% -> saturation.
A higher pressure has nu influence on saturation when the temperature remains constant, since it has no influence on e,E,x or X.
