Pressure and Volume are inversely proportionate. If the pressure is constant the volume will also be constant. The answer is D remain the same.

This is an application of Charles Law -- "the volume of a gas is directly proportional to its temperature at constant pressure" --, which is derived from the Ideal Gas Law:
P*V = n*R*T
If you are keeping pressure constant, P1 = P2
with no addition or subtraction of gas, n1 = n2
and R is the Universal Gas constant, thus:
V1/T1 = V2/T2, or:
V2/V1 = T2/T1
T1 = 30C = 303K
T2 = 90C = 363K
and you can do the arithmetic for yourself! Simple stuff!
