C. A,D
D. A,B,C,D

Answer

To solve the question regarding controlling pollution in big cities, we can analyze each option provided:

1. **Improving Traffic Conditions and Roads (Option A)**:
- Improving traffic conditions can reduce congestion, which in turn can lower the amount of fuel burned by vehicles. This can lead to a decrease in air pollution caused by vehicle emissions. Better road infrastructure can facilitate smoother traffic flow, reducing idle times and emissions.

2. **Roadside Plantation (Option B)**:
- Planting trees along roadsides can help in controlling air pollution. Trees absorb carbon dioxide and other pollutants, and they can also help in reducing noise pollution. This contributes positively to the urban environment, making it cleaner and more pleasant.

3. **Proper Disposal of Garbage and Domestic as well as Municipal Wastes (Option C)**:
- Proper waste disposal is crucial in controlling pollution. Improper disposal leads to littering, which can contaminate soil and water, and contribute to air pollution through the release of harmful gases from decomposing waste. Effective waste management practices, including recycling and composting, can significantly reduce pollution levels.

4. **Cannot be Controlled (Option D)**:
- This option suggests that pollution cannot be controlled, which is not accurate. While pollution is a significant issue, there are various strategies and measures that can be implemented to mitigate it.

**Conclusion**: The best approach to control pollution in big cities involves a combination of improving traffic conditions, roadside plantation, and proper waste disposal. Therefore, options A, B, and C are valid strategies.

**Final Answer**: The correct answer is A, B, and C.
