The maximum water vapour held in the atmosphere is

A. Absolute humidity

B. Saturation point

C. Relative humidity

D. Absolute transpiration

Answer: Option B

Solution(By Examveda Team)

The maximum water vapour held in the atmosphere is Saturation point.
The water-vapour content of the atmosphere varies from place to place and from time to time because the humidity capacity of air is determined by temperature.
At 30°C (86°F), for example, a volume of air can contain up to 4% water vapour. At -40°C (-40°F), however, it can hold no more than 0.2%.
