Which one of the following option gives the correct categorization of six animals according ot nitrogenous waste they give out?

Options

A. (a)(Ammonotelic) Pigeon, humans (Ureotelic) Aquatic amphibia, lizards (Uricotelic) Cockroach, frog.
B. (b)(Ammonotelic) Frog, lizards (Ureotelic) Aquatic amphibia, humans (Uricotelic) Cockroach, pigeon.
C. (c)(Ammonotelic) Aquatic amphibia (Ureotelic) Frog, humans (Uricotelic) Pigeon, lizard, Cockroach.
D. (d)(Ammonotelic) Aquatic amphibia (Ureotelic) Cockroach, humans (Uricotelic) Frog, Pigeon, lizard.

Answer

To categorize the six animals according to the nitrogenous waste they excrete, we need to understand the three main types of nitrogenous waste:

1. **Ammonotelic**: Organisms that excrete ammonia.
2. **Ureotelic**: Organisms that excrete urea.
3. **Uricotelic**: Organisms that excrete uric acid.

Now, let's analyze the options step by step:

### Step 1: Identify the waste types and corresponding animals

- **Ammonotelic**: Typically, aquatic animals like fish and some amphibians excrete ammonia directly into the water.
- **Ureotelic**: Mammals (including humans) and some amphibians excrete urea.
- **Uricotelic**: Birds (like pigeons) and terrestrial arthropods (like cockroaches) excrete uric acid.

### Step 2: Review the options provided

1. **Option 1**: Ammonotelic: Pigeon and Humans; Ureotelic: Aquatic Amphibia and Lizard; Uricotelic: Cockroach and Frog.
- **Analysis**: Incorrect. Pigeons and humans are not ammonotelic.

2. **Option 2**: Ammonotelic: Frog and Lizard; Ureotelic: Aquatic Amphibians; Uricotelic: Cockroach or Pheasant.
- **Analysis**: Incorrect. Frogs are not ammonotelic; they are ureotelic.

3. **Option 3**: Ammonotelic: Aquatic Amphibia; Ureotelic: Humans; Uricotelic: Pheasant, Lizard, or Cockroach.
- **Analysis**: Correct. Aquatic amphibians excrete ammonia, humans excrete urea, and lizards/cockroaches excrete uric acid.

4. **Option 4**: Ammonotelic: Aquatic Amphibia; Ureotelic: Cockroach or Human; Uricotelic: Frog, Pigeon, or Lizard.
- **Analysis**: Incorrect. Cockroaches are uricotelic, not ureotelic.

### Step 3: Conclusion

After analyzing all the options, the correct categorization according to the nitrogenous waste they excrete is given in **Option 3**.

### Final Answer:
**The correct answer is Option 3: Ammonotelic - Aquatic Amphibia; Ureotelic - Humans; Uricotelic - Pheasant, Lizard, or Cockroach.**
