The first response to this question would have been correct except that you must convert the temperature to Kelvin before using it in calculations.
The correct answer is A.

PV/T = PV/T
convert atmospheres to torr
760 torr / 1 atm = x torr / 1.59
x = 1208 torr
now plug into the first eqn
1208* 2.5 / 45 = 725 * x / 22
solve for x
x = 2.04 L , or (D)
