Solution

The correct option is B Both assertion and reason are correct but reason is not the correct explanation for assertion
The electrode at which oxidation takes place is an anode and the electrode at which reduction takes place is a cathode. Anode and cathode in electrochemical cells and electrolytic cells have opposite polarity. In Electrochemical cell anode is negatively charged, a cathode is positively charged whereas in electrolytic cell anode is positively charged and a cathodeis negatively charged.
$∴$ both assertion and reason are correct but reason is not the correct explanation of the 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
