High relative humidity decreases the evaporative process and as the temperature is increased, the relative humidity decreases. The comfort range for human body is the ambient temperature of 22 to 27°C with relative humidity ranging from __________ percent.

ANS:C - 45 to 50

The comfort range for the human body typically corresponds to an ambient temperature of 22 to 27°C with relative humidity ranging from 45 to 50 percent. This range provides optimal comfort for most individuals, balancing factors such as moisture content in the air, thermal sensation, and perspiration rate. Relative humidity within this range helps maintain a comfortable level of moisture in the air without causing discomfort due to excessive dryness or humidity. Therefore, the correct option is 45 to 50 percent.
