Flux is a mixture of silica oxide, calcium carbonate, manganese ore and dolomite.
Flux = sio2 + CaCo3 + Mn.
Flux = sio2 + CaCo3 + Mn.

Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.
The workpiece and the electrode melts forming the weld pool that cools to form a joint. As the weld is laid, the flux coating of the electrode disintegrates, giving off vapors that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination.
So answer C is right.
