Air is said to be saturated when :

A It contains maximum content of water vapour
B Its pressure is minimum
C Its thickness is maximum
D It blows over the barren land

Correct Answer: It contains maximum content of water vapour

Air is said to be saturated when the amount of water vapour in the air is the maximum possible at an existing temperature and pressure. Air is said to be saturated at 100 percent relative humidity when it contains the maximum amount of moisture possible at that specific temperature.
