A.

B.

C.
High and air is dry

AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Perspiration is maximum when temperature is High and air is humid. As air temperature increases, air can hold more water molecules, and its relative humidity decreases. When temperatures drop, relative humidity increases. High relative humidity of the air occurs when the air temperature approaches the dew point value. Temperature therefore directly relates to the amount of moisture the atmosphere can hold.
