Correct Answer: 3 to 4 percent
Solution : The correct option is 3 to 4 percent.
In general terms, at 20 degrees Celsius, which is a fairly common room temperature, the maximum water vapor content the air can hold is approximately 17 grams of water vapor per cubic meter of air which comes out to be 3 to 4 percent. The ratio of the quantity of water vapour present in the air to the maximum amount of water vapour the air could contain at a given temperature and pressure is known as relative humidity (RH). The relative humidity reaches 100% when the air is completely saturated with moisture and cannot contain any more.
