Answer:
c. Dew point temperature
Explanation:
Dew point temperature -
It is the temperature to which , the air need to be cooled in order to make it saturated with the water molecules , is known as the Dew point temperature .
And , when the it is cooled further more , the airborne water vapor will condense to form dew , liquid water .
Hence , from the question data , the correct option is c. Dew point temperature .
