Consider the following reaction at \[1000{}^\circ C\]

A.\[Zn(s)+\frac{1}{2}{{O}_{2}}(g)\to ZnO(s);\]\[\Delta G{}^\circ =-360kJ\,mo{{l}^{-1}}\]

B. \[C\left( gr \right)+\frac{1}{2}{{O}_{2}}(g)\to CO(g);\]\[\Delta G{}^\circ =-460kJ\,mo{{l}^{-1}}\]

Choose the correct statement at \[1000{}^\circ C\]

A) zinc can be oxidised by carbon monoxide.

B) zinc oxide can be reduced by graphite.

C) both statements [a] and [b] are true.

D) carbon monoxide can be reduced by zinc.
