Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Schottky defect is shown by ionic substances in which the cation and anion are of almost similar sizes. In Schottky defect, in order to maintain electrical charge neutrality, the number of missing cations and anions are equal.

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
