The correct answer is: D. The amount of water vapor in the air compared to the amount the air can hold.
Relative humidity measures how much water vapor is present in the air relative to the maximum amount the air can hold at a specific temperature. It is expressed as a percentage; for example, a relative humidity of 50% means the air contains half of the moisture it can potentially hold at that temperature.
