Relative humidity is a measure of the amount of water droplets in the air, as air get wet means the amount of water particle increases. So RH increases.

Relative humidity is about the quantity of water vapour dissolved in air. When air gets wet, part of vapour gets converted into liquid water. Thus the quantity of water vapour left in air decreases. So, the relative humidity decreases.

Relative humidity means Dry Bulb temp. It simply means outside air temp.
So, wet air means low temp which means low dry bulb temp, ie low humidity.
So, wet air means low temp which means low dry bulb temp, ie low humidity.

The answer is true because relative humidity tells about an amount of water vapor present and not on the amount of liquid present.
So as the air gets wet it decreases water vapor but increases liquid quantity so the given answer is correct.
So as the air gets wet it decreases water vapor but increases liquid quantity so the given answer is correct.

Please follow Psychometric chart, RH must increase.

Humidity - It is the amount of water vapor present in air, when the air gets wet water vapor decreases & air gets hot water vapor increases.

If air is getting wet that means the moisture content is increasing, which eventually results in increased relative humidity.
