Which of the following are examples of CFC refrigerants?

Explanation:
CFC refrigerants are chlorofluorocarbons that contain chlorine and are known for ozone layer depletion. R11 and R12 are classic examples of CFCs; they were widely used in older systems but are now phased out due to environmental concerns. The other options belong to different categories: R134a and R410A are HFCs (no chlorine), and R22 is an HCFC (contains chlorine but is not a CFC and is also being phased out). So, the refrigerants that fit the CFC group are R11 and R12.
