Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
de Broglie relation has significance for particles having low mass and high velocities
$λ \propto \frac{1}{m}$
for high mass $λ$ would be very small of no significance

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
