Solution

The correct options are
A $2 C u_{2} O + C u_{2} S \to 6 C u + S O_{2}$
C $2 C u_{2} S + 3 O_{2} \to 2 C u_{2} O + 2 S O_{2}$
The sulphide ore of copper is heated in the 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.

$2 C u_{2} S + 3 O_{2} \to 2 C u_{2} O + 2 S O_{2}$
$2 C u_{2} O + C u_{2} S \to 6 C u + S O_{2}$
