A) Airway resistance varies inversely with Lung Volumes.....In the way you increase the Lung Volume the resistance will decrease

Correct Answer correct answer

Correct answer is A)

An increase in pulmonary volume causes a decrease in airway resistance, which means that airway diameter increases. The airways are tethered to the surrounding tissues, which causes them to be pulled open when the lungs expand. This so-called radial traction phenomenon explains why it is easier for a person with obstructive pulmonary disease to breathe at higher than normal lung volumes.

This was just the answer as I was looking for....
