Solution

The correct option is C Assertion is correct but Reason is incorrect
An activity of an enzyme is $p H$ dependent.
With a change of $p H$ , the extent of protonation of the bases changes.
Change in $p H$ has no effect on the solubility of the enzyme in water.
Hence, the assertion is correct but reason is incorrect.

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
