उत्तर
Sulphur dioxide
Explanation:
Sulphur dioxide (SO2) is released mainly from burning fossil fuels containing sulfur. In the atmosphere, it reacts with water vapor to form sulfuric acid, which falls as acid rain. Acid rain causes damage to plants, aquatic life, buildings, and soil by increasing acidity and accelerating corrosion and nutrient depletion, making SO2 a major contributor to acid rain formation.
