Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
In the metallurgy of iron, limestone ( $C a C O_{3}$ ) is added to the ore.
It acts as a flux and forms calcium silicate $C a S i O_{3}$ (slag).

$C a C O_{3} \to C a O + C O_{2} ↑$

$C a O + S i O_{2} \to C a S i O_{3}$ Slag

Hence, both assertion and reason are correct and reason is the correct explanation for assertion.

Assertion – The non-fusible impurities present in iron ore are removed by $C a C O_{3}$ .

Reason: $C a C O_{3}$ which decomposes into $C a O$ and $C O_{2}$ . The $C a O$ formed reacts with $S i O_{2}$ to remove silica
