The correct Answer is:
**Step-by-Step Solution:** 1. **Understand the Context**: The question discusses the presence of chlorofluorocarbons (CFCs) in certain products despite the regulations set by the Montreal Protocol. CFCs are known to deplete the ozone layer, which protects the Earth from harmful ultraviolet (UV) radiation. 2. **Identify CFC Sources**: CFCs were commonly used in various products, particularly in refrigeration and air conditioning systems, as well as in some medical devices and office equipment. 3. **Analyze the Options**: The question provides four options: - Metered dose inhalers - Office equipment - Medical anesthetics - Coolants in old refrigerators and air conditioners 4. **Evaluate Each Option**: - **Metered dose inhalers**: Some older inhalers may contain CFCs, but many have been reformulated to use alternative propellants. - **Office equipment**: Generally, office equipment does not contain CFCs. - **Medical anesthetics**: Some medical anesthetics may have used CFCs in the past, but many have transitioned to safer alternatives. - **Coolants in old refrigerators and air conditioners**: This is a well-known source of CFCs, as older models often used CFCs as refrigerants. 5. **Select the Correct Options**: Based on the analysis, the two products that may still contain CFCs are: - Metered dose inhalers (older versions) - Coolants in old refrigerators and air conditioners 6. **Final Answer**: The two products that may contain CFCs are **metered dose inhalers** and **coolants in old refrigerators and air conditioners**. ---
