The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Acid Rain**: Acid rain is formed when gases like sulfur dioxide (SO2), nitrogen oxides (NO2), and carbon dioxide (CO2) are released into the atmosphere, primarily from the combustion of fossil fuels. These gases react with water vapor in the atmosphere to form acids. 2. **Formation of Acids**: The main acids formed from these gases are: - Sulfuric acid (H2SO4) from SO2. - Nitric acid (HNO3) from NO2. - Carbonic acid (H2CO3) from CO2. 3. **Impact on Agriculture**: When acid rain falls, it lowers the pH of the soil, making it more acidic. This change in soil pH can harm crops and affect agricultural productivity, leading to reduced yields. 4. **Impact on Aquatic Ecosystems**: Acid rain also affects bodies of water by lowering their pH. Aquatic organisms are sensitive to changes in pH, and a decrease can lead to harmful conditions for fish and other aquatic life, disrupting the ecosystem. 5. **Impact on Buildings and Structures**: Acid rain can corrode buildings and monuments, especially those made of limestone, marble, and metals. For example, structures like the Taj Mahal, which is made of marble, can suffer damage due to acid rain, leading to deterioration over time. 6. **Conclusion**: Given that acid rain is harmful to agriculture, aquatic ecosystems, and buildings/structures made of stone or metal, the correct answer is that acid rain is harmful to all of these. **Final Answer**: All of these (Option 4). ---
