B) absolute humidity
C) dew point
D) relative humidity

Question

Quizplus · Accepted Answer

The percentage of water vapor present in the air compared to that required for saturation is called relative humidity. Mixing ratio is the mass of water vapor present in the air compared to the mass of dry air. Absolute humidity is the mass of water vapor present per unit volume of air. Dew point is the temperature at which the air would need to cool at a constant pressure to become saturated with water vapor, leading to the formation of dew or frost. Therefore, the best answer is option D.
