Dew point can be best defined as the:
a. Absolute temperature at which air, upon heating, will evaporate moisture
b. Percentage of moisture that air can hold at a given temperature and pressure
c. Temperature that air will begin to evaporate moisture
d. Temperature at which air, upon cooling, becomes saturated, causing moisture to condense should the temperature drop further
e. Atmospheric pressure at which air will condense moisture
