Question

Humidity is the amount of __________ present in the air.

• A. oxygen
• B. nitrogen
• C. water vapour
• D. carbon dioxide

Answer 1

The correct option is C water vapour

Humidity is the amount of water vapour present in the air.
Humidity is one of the factors that affect the rate of evaporation.
When humidity is high, the rate of evaporation gets decreases. As a high amount of water droplets are already present in the atmosphere, it does not allow more water to get evaporated.
