Answer is Right!
Answer is Wrong!
The correct answer is C. Percentage.
Relative humidity is a measure of how much water vapor is in the air compared to the maximum amount of water vapor that the air can hold at that temperature. It is expressed as a percentage, with 100% being the maximum amount of water vapor that the air can hold at that temperature.
Grams and kilograms are units of mass, not percentage. A ratio is a comparison of two quantities, not percentage.
