\( \mathrm{E}^{\circ} \) of a cell \( \mathrm{aA}+\mathrm{bB} \longrightarrow \mathrm{cC}+\mathrm{dD} \) is
(a) \( \mathrm{E}+\mathrm{RT} \ln \frac{[\mathrm{a}]^{\mathrm{A}}[\mathrm{b}]^{\mathrm{B}}}{[\mathrm{c}]^{\mathrm{C}}[\mathrm{d}]^{\mathrm{D}}} \)
(b) \( \mathrm{E}+\frac{\mathrm{RT}}{\mathrm{nF}} \ln \frac{[\mathrm{C}]^{\mathrm{c}}[\mathrm{D}]^{\mathrm{d}}}{[\mathrm{A}]^{\mathrm{a}}[\mathrm{B}]^{\mathrm{b}}} \)
(c) \( \mathrm{E}+\frac{\mathrm{RT}}{\mathrm{nF}} \ln \frac{[\mathrm{C}]^{\mathrm{c}}[\mathrm{d}]^{\mathrm{D}}}{[\mathrm{A}]^{\mathrm{A}}[\mathrm{B}]^{\mathrm{B}}} \)
(d) \( \mathrm{E}+\frac{\mathrm{RT}}{\mathrm{nF}} \ln \frac{[\mathrm{a}]^{\mathrm{A}}[\mathrm{B}]^{\mathrm{B}}}{[\mathrm{C}]^{\mathrm{C}}[\mathrm{d}]^{\mathrm{D}}} \)
