What is right answer of this question?

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.

Name the material which is used for flux material?

Flux is a mixture of silica oxide, calcium carbonate, manganese ore and dolomite.

Flux = sio2 + CaCo3 + Mn.
