Solution

The correct option is B $C u_{2} S + 2 C u_{2} O \to 6 C u + S O_{2}$
The sulphide ore of copper is heated in air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged sulphide.
Self-reduction of CuS to Cu can be carried out in either Bessemer converter or Pierce-Smith converter.
$2 C u_{2} S + 3 O - 2 \to 2 C u_{2} O + 2 S O_{2}$
$2 C u_{2} O + C u_{2} S \to 6 C u + S O_{2}$
This is the final step in Bessemer converter.
