Correct Answer: Option C
Explanation

NO\(_2\) (nitrogen dioxide) is a covalent compound, not an ionic one. It is formed by the sharing of electrons between two non-metals: nitrogen and oxygen. Unlike ionic compounds, which typically involve the transfer of electrons from a metal to a non-metal, NO\(_2\) consists solely of non-metallic elements that form molecular bonds.
