Dew point is ________

A Amount of actual water vapour present per unit volume of air
B Incoming solar radiation
C A low pressure system in lower atmosphere
D A temperature at which a given sample of air becomes saturated

Correct Answer: A temperature at which a given sample of air becomes saturated

Dew points indicate the amount of moisture in the air. The higher the dew points, the higher the moisture content of the air at a given temperature. Dew point is a temperature at which a given sample of air becomes saturated.
