Solution

The correct option is A Aluminium
Anodising is an electrolytic process used to increase the thickness of the natural oxide layer on the surface of metal. Aluminium corrosion resistance is very good in untreated aluminium. Untreated aluminium has very good corrosion resistance in most environments. This is primarily because aluminium spontaneously forms a thin but effective oxide layer that prevents further oxidation.

Q. A sulphide ore is converted into metal oxide by the process of:
(a) carbonation
(b) roasting
(c) calcination
