Options

A. air pollution
B. water pollution
C. Both A and B
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the effects of fertilizers, pesticides, and insecticides on the environment. We need to identify which type of pollution they may cause.

2. **Identifying the Uses**: Fertilizers, pesticides, and insecticides are commonly used in agriculture. Their primary purpose is to enhance soil fertility and increase crop yield.

3. **Considering Excessive Use**: While these substances can be beneficial in moderation, excessive use can lead to negative environmental impacts.

4. **Analyzing Soil Pollution**: Overuse of fertilizers can lead to soil pollution. This happens when the soil becomes saturated with chemicals, which can deplete its natural fertility and make it barren over time.

5. **Examining Water Pollution**: When it rains or when irrigation occurs, excess fertilizers, pesticides, and insecticides can run off into nearby water bodies. This runoff causes water pollution, which can harm aquatic life and disrupt ecosystems.

6. **Evaluating the Options**:
- Option A (Air Pollution): Incorrect, as these substances do not primarily cause air pollution.
- Option B (Water Pollution): Correct, as they can lead to water pollution through runoff.
- Option C (Both A and B): Incorrect, since only water pollution is relevant here.
- Option D (None of the Above): Incorrect, as water pollution is indeed a consequence.

7. **Conclusion**: The correct answer is that fertilizers, pesticides, and insecticides may cause water pollution.

**Final Answer**: The correct option is **Water Pollution** (Option B).
