\( \mathrm{E}^{\circ} \) cell for the cell reaction \( 2 \mathrm{Fe}^{3+}+2 \mathrm{I}^{-} \rightarrow 2 \mathrm{Fe}^{2+}+\mathrm{I}_{2} \) is
(A) \( (2 \times 0.771-0.836)=1.006 \) volts
(B) \( (0.771-0.5 \times 0.536)=0.503 \) volts
(C) \( 0.771-0.536=0.235 \) volt
(D) \( 0.536-0.771=-0.235 \) volt
