Solution

The correct option is A $P V = n R T - \frac{n^{2} a}{V}$
Van der Waals equation for real gas is,
$(P + \frac{n^{2} a}{V}) (V - n b) = n R T$

For non zero forces of attraction between gas molecules and zero volume occupied by the gas molecules,
$a \neq 0 a n d b = 0$
Hence, the Van der Waals equation will be,
$P V = n R T - \frac{n^{2} a}{V}$
