Solution

The correct option is D $(I I)$ and $(I V)$
Correct option is not present because
(II) & (IV) reduction process are incorrect

Correction for wrong process are
2 ${A l}_{2} O_{3} + 9 C \to {A l}_{4} C_{3} + C O$
${C a}_{3} (P O_{4})_{2} + 5 C + 3 S i O_{2} ⟶ 2 P + 5 C O + 3 C a S i O_{3}$
