For the reaction,
\[
\begin{array}{rr}
\mathrm{C}+\mathrm{O}_{2} \longrightarrow \mathrm{CO}_{2} ; & \Delta H=-393 \mathrm{~J} \\
2 \mathrm{Zn}+\mathrm{O}_{2} \longrightarrow 2 \mathrm{ZnO} ; & \Delta H=-412 \mathrm{~J}
\end{array}
\]
Which one is correct?
(A) Carbon cannot reduce \( \mathrm{ZnO} \) to \( \mathrm{Zn} \)
(B) Oxidation of carbon is not feasible
(C) Oxidation of \( \mathrm{Zn} \) is not feasible
(D) Zn liberates more heat than carbon during oxidation
