Mosquito is

Options

A. Ammonotelic
B. Uricotelic
C. Ureotelic
D. Guanotelic

Answer

### Step-by-Step Solution:

1. **Understanding Excretory Products**:
- Organisms excrete waste products in different forms based on their habitat and physiology. The main types of excretory products are ammonia, urea, uric acid, and guanine.

2. **Defining Ammonotelic**:
- Ammonotelic organisms excrete ammonia as their primary nitrogenous waste. This is common in aquatic animals, like fish, because ammonia is highly soluble in water and can be easily diluted.

3. **Defining Uricotelic**:
- Uricotelic organisms excrete uric acid. This process is less toxic than ammonia and requires less water for excretion. Birds are classic examples of uricotelic organisms.

4. **Defining Ureotelic**:
- Ureotelic organisms excrete urea. Urea is less toxic than ammonia and can be stored for longer periods. Humans are an example of ureotelic organisms.

5. **Defining Guanotelic**:
- Guanotelic organisms excrete guanine. This form of excretion is observed in certain species like spiders and some insects.

6. **Identifying Mosquitoes**:
- Mosquitoes are classified as guanotelic organisms because they excrete guanine as their nitrogenous waste. This is advantageous as guanine is less toxic and requires minimal water for excretion.

7. **Conclusion**:
- Therefore, the correct classification for mosquitoes is that they are guanotelic.

### Final Answer:
Mosquitoes are guanotelic organisms.
