Solution

The correct option is A Bessemerisation
The process is called bessemerisation. $C u$ produced by Bessemerisation is known as blister $C u$ which is $95$ % pure. The balanced chemical reactions are as shown.
$2 C u_{2} S + 3 O_{2} \to 2 C u_{2} O + 2 S O_{2}$
$2 C u_{2} O + C u_{2} S \to 6 C u + S O_{2}$
