Text solutionVerified

There are only two carbides that are considered completely covalent; they are formed with the two elements that are most similar to carbon in size and electronegativity, boron (B) and silicon (Si). silicon carbide (SiC) is known as carborundum and is prepared by the reduction of silicon dioxide (SiO₂) with elemental carbon in an electric furnace.

so option (b) is correct
