Which of the following compounds is chlorine dioxide?

Explanation:
Recognize chlorine dioxide by its formula and composition. Chlorine dioxide is a distinct chlorine-oxygen compound with the formula ClO2. It is not chlorine gas (Cl2), not sodium hypochlorite (NaOCl), and not chloramine (NH2Cl). The option that literally names the compound chlorine dioxide is the correct identification, since it corresponds exactly to ClO2. This distinction matters because each substance has different chemical makeup, properties, and uses in water treatment.
