<reasoning>

Define covalent bonding

A covalent bond is formed by the sharing of electron pairs between atoms.

Identify the participating elements

This sharing typically occurs between nonmetal atoms that have similar, high electronegativities.

Evaluate the given options

• A describes ionic bonding.
• B describes metallic bonding.
• C is incorrect as metals form metallic bonds.
• D correctly identifies that covalent bonds form between two nonmetals.
