⭕ A. Summer
⭕ B. Winter
⭕ C. Pre-monsoon
⭕ D. Monsoon
📚 Explanation:
Air pollution disasters in India are most common in winter.
🔹 During winter, a phenomenon called temperature inversion occurs.
🔹 Warm air lies above cold air near the ground.
🔹 This prevents vertical mixing and traps pollutants close to the surface.
As a result, smog and air pollution levels rise sharply in many cities like Delhi.

👉 Therefore, the correct answer is: B. Winter
Key Points:
- Temperature inversion: traps pollutants.
- Low wind speed: reduces pollutant dispersion.
- High smog events: occur mainly in winter.
