Ans 22 : C) II only
The ideal gas law is given as :
pV = nRT
where p is pressure , V is volume , n is number of moles , R is universal gas constant and T is temperature.
So the variables inversely proportional to each other are : P ,V , such that when one increases the other decreases and vice versa.
