Solution

The correct option is C $2 C u F e S_{2} + O_{2} \to C u_{2} S + 2 F e S + S O$
In the extraction of copper, following reactions occur in Bessemer converter:
$2 C u_{2} S + 3 O_{2} \to 2 C u O + 2 S O_{2}$
$C u_{2} S + 2 C u_{2} O \to 6 C u + S O_{2}$
$2 C u_{2} S + 5 O_{2} \to 2 C u S O_{4} + 2 C u O$
$2 C u_{2} S + C u_{2} S O_{4} \to 4 C u + 2 S O_{2}$
$F e O + S i O_{2} \to F e S i O_{3}$

Roasting takes place in a furnace in the presence of a current of air. In this process, $2 C u F e S_{2} + O_{2} \to C u_{2} S + 2 F e S + S O$ , reaction takes place.
