The Correct Option is D
Solution and Explanation
Winter air conditioning focuses on providing comfortable indoor conditions during cold weather.
In winter, the air outside is usually cold and dry.
When this cold air enters a building, it often needs to be heated to a comfortable temperature.
However, heating alone can make the air even drier, causing discomfort like dry skin and irritation.
To maintain comfortable humidity levels, humidification is added along with heating.
This combination keeps the temperature warm and moisture at a pleasant level.
Cooling and dehumidification are summer processes.
Sensible cooling reduces temperature but is not needed in winter.
Therefore, heating and humidification is the correct answer for winter air conditioning.
