The equation of state of some gases can be expressed as
`(p+(a)/(V^(2)))(V-b)=RT`
where, `p` is the pressure, `V` is the volume, `T` is the absolute temperature and `a, b and R` are constant. The dimensions of `a` are

Options

A. `[ML^(5)T^(-2)]`
B. `[M^(-1)L^(5)T^(-2)]`
C. `[ML^(-1)T^(-2)]`
D. `[ML^(-5)T^(-2)]`
