Answer

To determine which statement is incorrect with respect to mosquitoes, we need to analyze the options provided.

1. **Understanding Mosquito Development**: Mosquitoes undergo a complete metamorphosis, which includes four distinct stages: egg, larva, pupa, and adult. Each stage has unique characteristics and can be visually distinguished from one another.

2. **Evaluating the Options**:
- **Option 1**: States that different stages of development in mosquitoes are distinguishable. This is correct.
- **Option 2**: Also states that different stages of development in mosquitoes are distinguishable. This is correct.
- **Option 3**: Again states that different stages of development in mosquitoes are distinguishable. This is correct.
- **Option 4**: If there is an option that contradicts the established facts about mosquito development, that would be the incorrect statement.

3. **Identifying the Incorrect Statement**: Since all the options analyzed so far affirm that the stages of development are distinguishable, we need to look for an option that might state something contrary to this fact.

4. **Conclusion**: If all options confirm that the stages are distinguishable, then the incorrect statement must be one that either misrepresents the life cycle of mosquitoes or suggests that the stages are not distinguishable.

**Final Answer**: The incorrect statement with respect to mosquitoes would be one that suggests that the stages of development are not distinguishable or misrepresents any aspect of their life cycle.
