The correct answer is: $100 \mathrm{~K}$
According to Gay Lussac's law $\mathrm{p} \propto \mathrm{T}$
$$
\begin{aligned}
\therefore & \frac{\mathrm{dp}}{\mathrm{p}} \times 100=\frac{\mathrm{dT}}{\mathrm{T}} \times 100 \\
1 &=\frac{1}{\mathrm{~T}} \times 100 \\
\Rightarrow & \mathrm{T}=100 \mathrm{~K}
\end{aligned}
$$
