17. Which of the following three statements concerning relative humidity values of 30% and 40% are true? Note that when the relative humidityis 30%, the air temperature may be diff erent than it is when the relativehumidity is 40%. A. It is possible that at a relative humidity of 30% there is a smaller partial pressure of water vapor in the air than there is at a relativehumidity of 40%.B. It is possible that there is the same partial pressure of water vapor in the air at 30% and at 40% relative humidity. C. It is possible that at a relative humidity of 30% there is a greater partial pressure of water vapor in the air than there is at a relative humidity of 40%.(a) A, B, and C (b) Only A and B (c) Only A and C (d) Only B and C(e) Only A
