The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding SO2 Pollution**: Sulfur dioxide (SO2) is a significant air pollutant that can have harmful effects on the environment and living organisms. It is primarily produced from industrial processes, burning fossil fuels, and volcanic eruptions. 2. **Identifying Sensitive Organisms**: Certain organisms are particularly sensitive to air pollution, including SO2. These organisms can serve as indicators of air quality. 3. **Role of Lichens**: Lichens are symbiotic associations between fungi and algae or cyanobacteria. They are known to be highly sensitive to air pollution, especially sulfur dioxide. Because of their sensitivity, they are often used as bioindicators to assess the level of air pollution in a given area. 4. **Conclusion**: Therefore, the organisms that are sensitive to SO2 pollution are lichens. Their presence or absence in an environment can indicate the level of sulfur dioxide pollution. **Final Answer**: Lichens are the organisms sensitive to SO2 pollution. ---
