Answer

**Step-by-Step Solution:**

1. **Understanding Nonbiodegradable Pollutants**:
- Nonbiodegradable pollutants are substances that cannot be broken down by natural processes. They remain in the environment for a long time without decomposing.

2. **Identifying Examples**:
- We need to analyze the options given: nude spring, green leaf, DDT, and cow dung.
- Nude spring and green leaf are organic materials that can decompose, while cow dung is also biodegradable.

3. **Analyzing DDT**:
- DDT (Dichloro-Diphenyl-Trichloroethane) is a synthetic pesticide that is known for its stability and resistance to degradation.
- It does not dissolve in water and accumulates in the fatty tissues of living organisms.

4. **Effects of DDT**:
- DDT is responsible for bio-magnification, where its concentration increases as it moves up the food chain.
- It can also harm microbial life in the soil, disrupting ecosystems.

5. **Conclusion**:
- Based on the analysis, the correct answer to the question "A nonbiodegradable pollutant is" is DDT.
