A. Mixing ratio
B. Absolute humidity
C. Dew point
D. Relative humidity
E. Specific humidity

Air with a 50 percent relative humidity actually contains one-half the amount of water vapor required for saturation. Air with a 100 percent relative humidity is said to be saturated because it is filled to capacity with water vapour.
