13. 

The relative humidity is defined as

[A]. the mass of water vapour present in 1 m3 of dry air
[B]. the mass of water vapour present in 1 kg of dry air
[C]. the ratio of the actual mass of water vapour in a unit mass of dry air to the mass of water vapour in the same mass of dry air when it is saturated at the same temperature and pressure.
[D]. the ratio of actual mass of water vapour in a given volume of moist air to the mass of water vapour in the same volume of saturated air at the same temperature and pressure

I think its mass of dry air instead of volume.

Amal said: (Jan 2, 2016)  
It should be mass that is option [C] is correct.

Love Bhardwaj said: (May 20, 2016)  
As per my knowledge, It should be option C.

Nahom said: (Sep 26, 2016)  
I thick option C is correct.

I agree with the given answer i.e option D.

Shubh said: (Jan 24, 2017)  
Yes, I too agree with the option C.

Lambo said: (Apr 9, 2017)  
Relative humidity is the ratio of the water vapor density (mass per unit volume) to the saturation water vapor density. So, option D is the correct answer.

Demudu Babu said: (May 30, 2017)  
I agree with the given answer Option D.

Saurabh said: (Oct 14, 2017)  
Option c is the definition of the degree of saturation.
