Using the gas law equation: P1/T1 = P2/T2
where P1 and T1 are the initial pressure and temperature, P2 and T2 are the final pressure and temperature.

Converting temperature to Kelvin:
T1 = (15+273)K = 288K 
T2 = (45+273)K = 318K

Substituting values:
P1/T1 = P2/T2 
300kPa / 288K = P2 / 318K 
P2 = (300kPa / 288K) * 318K = 330kPa

Therefore, the gauge pressure at 45°C is 330 kPa, which corresponds to answer B).
