Solution

The correct options are
C $F e_{2} O_{3} + 3 C \to 2 F e + 3 C O$
D $C a O + S i O_{2} \to C a S i O_{3}$
Solution:

Extraction of iron is based on the reduction of Haematite $F e_{2} O_{3}$ with carbon.

In reduction zone following reactions took place:

$F e_{2} O_{3} + C O \to 2 F e o + C O_{2}$

$F e O + C O \to F e + C O_{2}$

In fusion Zone at higher temperature following reaction took place:

$F e_{2} O_{3} + 3 C \to 2 F e + 3 C O$

Reaction in slag formation:

$C a O + S i O_{2} \to C a S i O_{3}$
Hence option C and D are correct as this reaction doesn't took place in reduction zone.
