A non-ideal gas, follows the equation
\[ P=\frac{R T}{V_{m}}\left[1+\frac{B}{V_{m}}\right] \]
where B is a function of temperature only. The deviation in internal energy from that of an ideal gas, $\mathrm{U}-\mathrm{U}_{\text {ideal }}$ ideal is given by
(a)$-\frac{\mathrm{RT}}{\mathrm{V}_{\mathrm{m}}}\left(\frac{\partial \mathrm{B}}{\partial \mathrm{T}}\right)_{\mathrm{V}}$
(b)$-\frac{\mathrm{RT}^{2}}{\mathrm{V}_{\mathrm{m}}}\left(\frac{\partial \mathrm{B}}{\partial \mathrm{T}}\right)_{\mathrm{V}}$
(c)$-\frac{\mathrm{RT}^{2}}{\mathrm{V}_{\mathrm{m}}} \mathrm{B}$
(d)$-\frac{R T}{V_{m}} B$
