Solution

The correct options are
C $F e_{2} O_{3} + 3 C \to 2 F e + 3 C O$
D $C a O + S i O_{2} \to C a S i O_{3}$
Reactions in option $A$ and $B$ occurs in reduction zone.
$F e_{2} O_{3} + C O \to 2 F e O + C O_{2}$
$F e O + C O \to F e + C O_{2}$
Reaction in option $C$ occurs in fusion zone at higher temperature with $F e_{2} O_{3}$ which escapes reduction zone.
Reaction in option $D$ occurs in slag formation zone.

Hence, option C and D are correct.
