D. Cloudy Skies, calm winds and humid air.

Explanation:

These sets of conditions are needed for the day to night changes in temperature. This can be understood from the temperature inversions found at various altitudes and latitudes.   As the cold air underlies the warm air, the late-night inversion or temperature changes occur after the sun has set in the horizon and the air is humid and calm, the cloudy skies as during daytime the sun above warms the air and this rising air creates a low pressure. Basic funda is that thick layer of clouds blocks or cut the sun rays from reaching the ground creating a blocking effect the heat the earth has already absorbed is unable to move out or circulate due to the winds blowing are also calm and air above gets trapped , but at times this changes as the sun comes out. At night if the cloud cover remains the same more humidity is generated and this further adds to heat being radiate outwards from the earth in the form of long waves.
