Which explains why carbon (C) is such a versatile element?

It can form four covalent bonds.

It can form only ionic bonds.

It can form both ionic and covalent bonds.

It can form three ionic bonds.

it can form 4 covalent bonds.

Explanation:

i just took the test

It can form four covalent bonds.

Explanation:

Carbon is a versatile element because it forms covalent bonds i. e. Single, double, triple and ring or branched etc with other atoms. It forms only covalent bond not ionic bond because carbon has four electrons in its outermost shell. If they make ionic bond, they have to gain 4 electrons and become anion or it has to lose 4 electrons and become cation. So they prefer to make covalent bonds.
