Chemistry Question on General Principles and Processes of Isolation of Elements

At 1000?C1000^?C, Zn(s)+12O2(g)→ZnO(s)Zn_{\left(s\right)}+\frac{1}{2}O_{2\left(g\right)} \to ZnO_{\left(s\right)}; ΔG∘=−360 kJ mol−1\Delta G^{\circ} = -360\,kJ\,mol^{-1} C(s)+12O2(g)→CO(g)C_{\left(s\right)} + \frac{1}{2}O_{2\left(g\right)} \to CO_{\left(g\right)}; ΔG∘=−460 kJ mol−1\Delta G^{\circ} = -460\,kJ\,mol^{-1} The correct statement is
