A mixture of magnesium powder and zinc oxide is heated strongly. The equation for the reaction is Mg(s)+ZnO(s)→MgO(s)+Zn(s)\text{Mg}(s) + \text{ZnO}(s) \rightarrow \text{MgO}(s) + \text{Zn}(s)Mg(s)+ZnO(s)→MgO(s)+Zn(s). During this reaction, which of these substances is oxidised?
Zinc oxide
Magnesium oxide
Magnesium
Zinc
