The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding BOD**: BOD stands for Biochemical Oxygen Demand. It is a key parameter used to assess the quality of water. 2. **Definition of BOD**: BOD measures the amount of oxygen that microorganisms will consume while decomposing organic matter in water at a certain temperature over a specified time period. 3. **Relation to Organic Pollutants**: The higher the BOD value, the more organic pollutants are present in the water. This is because a higher demand for oxygen indicates that there is more organic matter for microorganisms to break down. 4. **Conclusion**: Therefore, BOD is a measure of the organic pollutants in water. It reflects the degree of pollution and the potential impact on aquatic life. 5. **Incorrect Options**: Other options like oxides of sulfur, phosphorus, nitrogen in air, inorganic pollutants, and particulate matter do not relate directly to BOD, as they pertain to different types of pollution or pollutants. **Final Answer**: BOD is a measure of organic pollutants in water. ---
