What kind of bond does carbon usually form from

The most common type of bond formed by carbon is a covalent bond in which carbon shares electrons with other atoms. There are three major types of covalent bonds: single, double, and triple bonds. A carbon atom itself can form four single bonds. Since carbon has four valence electrons, it forms covalent bonds with four neighboring carbon atoms.

Explanation:

Carbon most often forms a covalent bond with other atoms. If the bond is with another carbon atom, it is a pure covalent (or nonpolar covalent) bond. If it is with another atom, a polar covalent bond is formed.

The most common oxidation state of carbon is +4 or -4.

Less commonly, carbon forms ionic bonds with other atoms. This occurs when there is a large electronegativity difference between carbon and the other atom.

So, it usually forms covalent bonds. So D.
