A sulphide ore is first converted into its oxide before reduction. This is done because :

A

the enthalpy of formation of `CO_2` is more than that of `CS_2`.

B

a metal sulphide is generally more stable than the metal oxide.

C

no reducing agent is found suitable for reducing a sulphide ore.

D

a sulphide ore cannot be reduced at all.
