Critical constants for a real gas are given as

$\begin{array}{r}{T}_C=180\mathrm{K}\\ V_C=0.1231\mathrm{L}/\mathrm{mole}\\ P_C=45\mathrm{atm}\end{array}$

The correct statement for the real gas is :

The actual volume of single gas molecule is $\left(\frac{0.123\times {10}^{-3}}{6.023\times {10}^{23}}\right)cc$

$b=3\times 0.123\mathrm{L}{\mathrm{mol}}^{-1}$

Gas cannot be liquefied at 200 K

The Boyle's temperature is less than 1.80 K
