Solution

The correct option is B curve B
At low pressure, the gas will show ideal behaviour and hence $\frac{P V}{R T} = n u m b e r o f m o l e s$ which will remain constant.
But as pressure increases, there will be dominant interatomic forces and actual volume will be less due to finite size. Hence, B curve will be followed.
