Solution

The correct option is D
slag

$C a C O_{3} Δ - \to C a O + C O_{2}$

The coke further reacts with this carbon dioxide to form carbon monoxide:
$C O_{2} + C ⟶ 2 C O$

Reduction:
$F e_{2} O_{3} + 3 C ⟶ 2 F e + 2 C O$

The $C a O$ from the added limestome (calcium carbonate) reacts with silica forming slag:
$C a O + S i O_{2} ⟶ C a S i O_{3}$
