Model Answer
In ZnO + C → Zn + CO, ZnO (zinc oxide) is reduced (loses oxygen) and C (carbon) is oxidised (gains oxygen).
Explanation
Oxidation = gain of oxygen; Reduction = loss of oxygen. ZnO loses oxygen to become Zn (reduced); C gains oxygen to become CO (oxidised). Carbon acts as the reducing agent here. Examiners expect both substances named with reason in one line for 1 mark.
