Ideal Gas Law: PV=nRT

R is the universal gas constant of 8.31.

T is temperature in Kelvins. ( add 273 to the Celsius temperature ( 273 +97 = 370).

Fill in the letters with the given information:

P(45.0) = (2.40)(8.31)(370)

Simplify the right side:

P(45.0) = 7379.28

Divide both sides by 45.0

P = 7379.28 / 45.0

P = 163.984

Round to 164

Answer is D.
