96kPa. Option C is correct
According to Gay Lussac's law, the pressure of a given mass of gas is directly proportional to the temperature provided that the volume is constant. Mathematically:
[tex]\begin{gathered} P\alpha T \\ P=kT \\ k=\frac{P_1}{T_1}=\frac{P_2}{T_2} \end{gathered}[/tex]Substituting the given parameters to determine the new pressure P2
[tex]\begin{gathered} P_2=\frac{P_1T_2}{T_1} \\ P_2=\frac{65\times(167+273)}{(25+273)} \\ P_2=\frac{65\times440}{298} \\ P_2=\frac{28600}{298}=95.97kPa \\ P_2\approx96kPa \end{gathered}[/tex]Therefore the new pressure is 96kPa
