Answer 1

None of the above responses are correct. When the air temperature is equal to the dew point temperature, the relative humidity is 100%, but there is no evaporation or condensation occurring. This is because the air is saturated with water vapor at its dew point temperature, meaning it can no longer hold any more moisture.
