On the basis of information available from the reaction
\( \frac{4}{3} \mathrm{Al}+\mathrm{O}_{2} \longrightarrow \frac{2}{3} \mathrm{Al}_{2} \mathrm{O}_{3}, \Delta \mathrm{G}=-827 \mathrm{~kJ} \mathrm{~mol}^{-1} \) of \( \mathrm{O}_{2} \), the minimum emf required to carry out electrolysis of \( \mathrm{Al}_{2} \mathrm{O}_{3} \) is :
(A) \( 2.14 \mathrm{~V} \)
(B) \( 4.28 \mathrm{~V} \)
(C) \( 6.42 \mathrm{~V} \)
(D) \( 8.56 \mathrm{~V} \)
