Answer:
B
Explanation:
When the air temperature is equal to the dew point temperature, the relative humidity would be 100% and condensation occurs.
The dew point temperature is a temperature at which the air is saturated with water vapor and some of it begins to condense as liquid water. As the air temperature cools further, more and more water condenses as liquid water and this is essentially what constitutes precipitation.
The correct option is B.
