Which is correctly matched

Options

A. Man - Ureotelic
B. Birds - Ammonetellic
C. Fish - Uricotelic
D. Frog - Uricotelic

Answer

To solve the question "Which is correctly matched?" regarding the excretory products of different organisms, we need to analyze the excretory mechanisms of each organism mentioned: frogs, men (humans), birds, and fishes.

### Step-by-Step Solution:

1. **Identify the Excretory Products:**
- **Frogs:** Frogs are primarily ureotelic, meaning they excrete urea as their main nitrogenous waste product. However, it is important to note that frog tadpoles, which live in water, excrete ammonia (ammonotelic).
- **Men (Humans):** Humans are also ureotelic, excreting urea as their primary nitrogenous waste.
- **Birds:** Birds are uricotelic, which means they excrete uric acid as their nitrogenous waste. This method conserves water, which is crucial for survival in their environments.
- **Fishes:** Most fishes are ammonotelic, meaning they excrete ammonia, which is highly toxic but is diluted in water.

2. **Match Each Organism with Its Excretory Product:**
- **Frogs:** Ureotelic (correct)
- **Men:** Ureotelic (correct)
- **Birds:** Uricotelic (correct)
- **Fishes:** Ammonotelic (correct)

3. **Evaluate the Given Options:**
- The question provides options that may incorrectly match these organisms with their excretory products. Based on our analysis:
- Frogs are ureotelic, not uricotelic.
- Men are ureotelic.
- Birds are uricotelic, not aminotelic.
- Fishes are ammonotelic, not ureotelic.

4. **Conclusion:**
- The correctly matched statement is: **Men are ureotelic.**

### Final Answer:
The correct match is: **Men are ureotelic.**
