  • ✓
    Be reduced by carbon monoxide only.
  • B
    Be reduced by both carbon monoxide and carbon.
  • C
    Be reduced by carbon only.
  • D
    Not be reduced by both carbon and carbon monoxide.
✓

Answer

Correct option: A.
Be reduced by carbon monoxide only.
Below the point $A,$ Gibbs free energy change for the formation of $\mathrm{CO}_2$ from $CO$ has lower value than Gibb’s free energy change for the formation of $\text{FeO}.$ Hence $\text{FeO}$ will be reduced by $CO$ only below point $A.$
