A. At the time when the air temperature is highest
B. In the middle of the afternoon
C. At the time when the air temperature is lowest
D. Just before sunrise
E. About midnight

The relative humidity is usually highest around sunrise when the overnight low temperature is frequently close to the dew point. The humidity drops during the day as the temperature rises and usually reaches its lowest value in the middle or late afternoon when the day’s maximum temperature is recorded.
