B.

Answer
C.
The moisture present in it begins to condense
D.
None of the above

Answer: Option B

Solution

Answer: Option B
Solution:
Wet-bulb temperature. The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water-soaked cloth (wet-bulb thermometer) over which air is passed. At 100% relative humidity, the wet-bulb temperature is equal to the air temperature (dry-bulb temperature) and it is lower at lower humidity.
