Enthalpy of dry air is greater than wet air. When we plot this on psyschro chart we get a increase in relative humidity as enthalpy increases.

The ratio of the actual mass of water vapour in a given volume of moist air to the mass of water vapour in the same volume of saturated air at the same temperature and pressure.
Air is getting dry means amount of water vapour in the given volume is creasing.
So, the correct answer ''decreases''.
Air is getting dry means amount of water vapour in the given volume is creasing.
So, the correct answer ''decreases''.

Rule of Thumb : Relative humidity doubles with each 20 degrees (Fahrenheit) decrease, or halves with each 20 degrees increase in temperature.
Generally, as temperature goes up, relative humidity goes down and vice versa.

Yes, for dry air RH = 0%,
For sat air RH = 100%.
So, it should be decreased.
For sat air RH = 100%.
So, it should be decreased.
