Answer

To solve the question regarding which species is the least affected by polluted rivers, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: The question highlights the negative impact of industrialization on the environment, specifically focusing on water pollution caused by waste materials dumped into rivers and lakes.

2. **Identify the Species**: The options provided are Kingfish, Goldfish, Parrot, and Turtle. We need to analyze which of these species is least affected by polluted water.

3. **Analyze Each Species**:
- **Kingfish**: This is a type of fish that lives in water. Fish are generally very sensitive to water pollution and can be severely affected by toxins and waste in their habitat.
- **Goldfish**: Similar to Kingfish, Goldfish are also fish and are susceptible to water pollution. They can suffer from health issues due to contaminated water.
- **Turtle**: Turtles are aquatic reptiles that can also be affected by polluted water, though they may have some resilience compared to fish.
- **Parrot**: Parrots are terrestrial birds and do not live in water. Therefore, they are not directly affected by water pollution.

4. **Determine the Least Affected Species**: Since parrots do not inhabit polluted rivers or lakes, they are the least affected by water pollution compared to the other aquatic species listed.

5. **Conclusion**: The species that is least affected by polluted rivers is the **Parrot**.
