The clean water would have a BOD value of more than 17.

Answer

**Step-by-Step Solution:**

1. **Understanding BOD**: BOD stands for Biochemical Oxygen Demand. It measures the amount of oxygen consumed by microorganisms when decomposing organic matter in water under aerobic conditions (in the presence of oxygen).

2. **BOD Values**:
- Clean water typically has a BOD value of less than 5 parts per million (ppm).
- Highly polluted water has a BOD value greater than 17 ppm.

3. **Analyzing the Statement**: The statement claims that "The clean water would have a BOD value of more than 17."

4. **Evaluating the Truth of the Statement**: Since we know that clean water has a BOD value of less than 5 ppm, the statement that clean water has a BOD value of more than 17 ppm is incorrect.

5. **Conclusion**: Therefore, the statement is false.

**Final Answer**: The clean water would have a BOD value of more than 17 is false.
