Best answer
The correct option is (b) Tungsten carbide

For explanation I would say: Tungsten carbide (WC) belongs to the carbide class of engineering ceramics. It is used for cutting tools. Silicon carbide and boron carbide are used as abrasive, whereas vanadium carbide and tantalum carbide are used as wear-resistant materials. Chromium carbide is used as wear coating.
