Solution
The correct option is B decreases
Relative humidity may be defined as the ratio of the water vapour density (mass per unit volume) to the saturation water vapour density.
Actual vapour pressure is a measurement of the amount of water vapour in a volume of air and increases as the amount of water vapour increases. Air that attains its saturation vapour pressure has established an equilibrium with a flat surface of the water. That means an equal number of water molecules are evaporating from the surface of the water into the air as are condensing from the air back into the water.
So as temperature increases, relative humidity decreases while absolute humidity increases.
Hence, the correct option is B
