(D) In the Ellingham diagram, the reduction of $FeO$ by carbon to produce $CO$ is represented by the reaction: $2FeO + 2C \rightarrow 2Fe + 2CO$. This reaction is spontaneous when the Gibbs free energy change $(\Delta G^\circ)$ for the coupled reaction is negative. Looking at the diagram, the line for the oxidation of carbon to $CO$ $(2C + O_2 \rightarrow 2CO)$ intersects the line for the oxidation of iron to $FeO$ $(2Fe + O_2 \rightarrow 2FeO)$ at point $A$. At temperatures above point $A$, the line for $2C + O_2 \rightarrow 2CO$ lies below the line for $2Fe + O_2 \rightarrow 2FeO$, meaning the reduction of $FeO$ by $C$ becomes thermodynamically favorable $(\Delta G^\circ Therefore, the reduction occurs at temperatures above point $A$.

The temperature at which carbon reduces $FeO$ into iron and produces $CO$ is:
