Solution

The correct option is D Both Assertion and Reason are incorrect
Both $2 p_{x}$ and $2 p_{y}$ orbitals have equal energy ( $2 p$ orbitals are degenerate), there is no possibility of electron transition and hence, no energy is released and thus, no spectral line will be observed

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
