As we learnt in 

Vander waal equation for real gas -

\left (p+\frac{an^{2}}{v} \right )(V-nb)=nRT

- wherein

a, b : Vander waal Constants, P- Pressure, V- Volume, n- No. of moles, R- Gas Constant, T- Temperature

 

\left ( P+\frac{an^{2}}{V^{2}} \right )\left ( V-nb \right )= nRT


Option 1)

Constants a & b are small

Correct

Option 2)

a is large & b is small

Incorrect

Option 3)

 a is small & b is large

Incorrect

Option 4)
