Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Alkali metal dissolves in liquid ammonia and produces solvated cations and anions.
$M + (x + y) N H_{3} \to [M (N H_{3})_{x}]^{+} + [e (N H_{3})_{y}]^{-}$
Above 3M concentration, the solutions are no longer blue but are bronze/ copper-bronze coloured with a metallic luster due to the formation of metal ion clusters.

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
