Answer : Option A
Explanation :
The air's capacity for water vapour increases as air temperature increases. Air with a temperature of 30°C can hold more than three times as much water vapour as air at 10°C. Relative humidity varies significantly when the temperature changes, even when the actual amount of water vapour in the air remains the same.
