Consider the following table i
\begin{tabular}{lll}
Gas & $\mathrm{a} /\left(\mathrm{k} \mathrm{Pa} \mathrm{dm}^6 \mathrm{~mol}^{-1}\right)$ & $\mathrm{b} /\left(\mathrm{dm}^3 \mathrm{~mol}^{-1}\right)$ \\
A & 642.32 & 0.05196 \\
B & 155.21 & 0.04136 \\
C & 431.91 & 0.05196 \\
D & 155.21 & 0.4382
\end{tabular}
a and b are van der Waals constants. The correct statement about the gases is:
