[tex]\boxed {\boxed {\sf D. \ H_2O_2}}[/tex]

Explanation:

A covalent compound is a molecule made up of covalent bonds, where the atoms share pairs of valence electrons. These compounds consist of two or more nonmetals.

Essentially, if a compound contains a metal, it is an ionic or metallic compound, not a covalent compound.

A. NaCl

This is sodium chloride. It contains sodium (Na) and chlorine (Cl). Sodium is a metal, so this is ionic.

B. CaO

This is calcium oxide. It contains calcium (Ca) and oxygen (O). Calcium is a metal, so this is ionic.

C. MgS

This is magnesium sulfide. It contains magnesium (Mg) and sulfur (S). Magnesium is a metal, so this is ionic.

D. H₂O₂

This is hydrogen peroxide. It contains hydrogen (H) and oxygen (O). Both of these elements are non-metals, so this is a covalent compound.

The correct choice is D. H₂O₂
