hey but coke is not used at all...self reduction takes place.
so i think the answer should be only option 4.
more than one :
1)coke acts as reducing agent
2)Cu2S remain unaffect in roasting
3)final product we get is Blister Cu due to release of CO2
4)In bessemer furance only self reduction takes place not slag formation.

is dat the rite ans is 1 and 4
in 3 SO2 gas will be formed and not carbon-di-oxide
in 2 blister copper sulphide gets converted into copper oxide and only some part remains unaffected not the whole of copper oxide
slag formation occurs at the smelting process.
