C. No variant is completely wiped out
D. All of the above

Answer

To determine which statement is incorrect regarding the effects of the Industrial Revolution in England, we will analyze each statement provided in the question step by step.

### Step-by-Step Solution:

1. **Analyze Statement 1: "Dark colored peppered moth is more in urban area."**
- After the Industrial Revolution, pollution increased, leading to a rise in the population of dark-colored peppered moths (Biston betularia) in urban areas. This was due to the phenomenon known as industrial melanism, where darker moths had a survival advantage against predators in polluted environments. However, as pollution levels decreased later on, the light-colored moths began to reappear and dominate again.
- **Conclusion:** This statement is **incorrect** as it implies that dark-colored moths remained prevalent in urban areas after the Industrial Revolution.

2. **Analyze Statement 2: "Light colored peppered moth is more in rural area."**
- In rural areas, where pollution was lower, light-colored peppered moths were indeed more common. However, this statement can be misleading because it implies that light-colored moths were the dominant form in rural areas during the peak of industrialization, which was not entirely accurate.
- **Conclusion:** This statement is also **incorrect** as it suggests a consistent dominance of light-colored moths in rural areas without considering the context of industrialization.

3. **Analyze Statement 3: "No variant is completely wiped out."**
- This statement suggests that neither the light nor dark variants of the peppered moth were completely eradicated. While the dark variant saw a significant increase during the industrial period, the light variant faced a decline. However, it is true that some light-colored moths survived, especially in less polluted areas.
- **Conclusion:** This statement is **correct** as it indicates that while populations changed, no variant was completely wiped out.

4. **Analyze Statement 4: "All of the above."**
- This statement claims that all previous statements are incorrect. Given that the third statement is correct, this statement cannot be true.
- **Conclusion:** This statement is **incorrect** because not all previous statements are false.

### Final Answer:
The incorrect statement after the Industrial Revolution in England is **Statement 1**: "Dark colored peppered moth is more in urban area."
