Options

A. Television
B. Air conditioner
C. Microwave oven
D. Washing machine

Explanation

To determine which household appliance leads to the release of chlorofluorocarbons (CFCs) into the air, we can analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Chlorofluorocarbons (CFCs)**:
- CFCs are chemical compounds that were commonly used in various applications, particularly as refrigerants in cooling systems. They are known to deplete the ozone layer, which protects the Earth from harmful ultraviolet radiation.

2. **Analyzing the Options**:
- **a. Television**: Televisions do not use CFCs in their operation. They primarily use electrical components and do not involve any cooling systems that would release CFCs.
- **b. Air Conditioner**: Air conditioners use refrigerants to cool the air. Historically, many air conditioners used CFCs as refrigerants, leading to their release into the atmosphere.
- **c. Microwave Oven**: Microwave ovens work by using electromagnetic radiation to heat food. They do not use CFCs in their operation.
- **d. Washing Machine**: Washing machines do not typically use CFCs. They mainly use water and detergent for cleaning clothes.

3. **Conclusion**:
- Based on the analysis, the appliance that leads to the release of chlorofluorocarbons into the air is **b. Air Conditioner**.

### Final Answer:
**b. Air Conditioner**
