Which statement is true about CFCs?

Which statement is true about CFCs?

• A. They contain hydrogen
• B. They contain carbon, fluorine, and chlorine
• C. They contain oxygen
• D. They are composed of hydrogen and chlorine only

Answer: (B)

Chlorofluorocarbons are carbon-based compounds that include chlorine and fluorine as the key halogen components. The name itself points to carbon with chlorine and fluorine atoms, and they do not ordinarily include oxygen in their basic structure. Hydrogen may appear in related groups (like HCFCs), but classic CFCs typically have no hydrogen. So, describing CFCs as containing carbon, fluorine, and chlorine matches their actual makeup. The other statements misstate the composition by implying hydrogen is always present, or that oxygen is part of the molecule, or that hydrogen and chlorine are the only elements.
