Select the correct match of animal, excretory organs and product

Options

A. Salamander - kidney - urea
B. Peacock - kidney - urea
C. Housefly - renal tubules - uric acid
D. Labeo - nephridal tubes - ammonia

Answer

To solve the question of matching animals with their respective excretory organs and products, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Analyze the first option: Salamander, Kidney, Urea**
- Salamanders are amphibians.
- Their primary excretory organs are kidneys.
- They excrete urea as their nitrogenous waste product.
- **Conclusion:** This option is correct.

2. **Analyze the second option: Peacock, Kidney, Urea**
- Peacocks are birds.
- They have metanephric kidneys as their excretory organs.
- Birds excrete uric acid, not urea.
- **Conclusion:** This option is incorrect because it states urea instead of uric acid.

3. **Analyze the third option: Housefly, Renal Tubules, Uric Acid**
- Houseflies are insects.
- They possess Malpighian tubules as their excretory organs, not renal tubules.
- Houseflies excrete uric acid.
- **Conclusion:** This option is incorrect because it states renal tubules instead of Malpighian tubules.

4. **Analyze the fourth option: Labio, Nephrodial Tubules, Ammonia**
- Labio refers to a type of fish.
- Fish primarily have kidneys for excretion, but they also excrete through their gills and skin.
- Fish excrete ammonia as their nitrogenous waste.
- **Conclusion:** This option is incorrect because it states nephrodial tubules instead of kidneys.

### Final Conclusion:
- The only correct match is **Option 1: Salamander, Kidney, Urea**.
