B. b) `{:("Ammonotelic","Ureotelic","Uricotelic"),("frog, lizards","Aquatic amphibia,humans","Cockroach,frog"):}`
C. c) `{:("Ammonotelic","Ureotelic","Uricotelic"),("Aquatic animals","Frog, amphibia,humans","Pigeon, lizards, cockroach"):}`
D. d) `{:("Ammonotelic","Ureotelic","Uricotelic"),("Aquatic animals","Cockroach, amphibia, humans","Pigeon, lizards"):}`

Explanation

To solve the question regarding the categorization of animals based on the type of nitrogenous waste they excrete, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Nitrogenous Wastes**:
- There are three main types of nitrogenous wastes produced by animals: ammonia, urea, and uric acid.

2. **Identify Ammonotelic Organisms**:
- Ammonotelic organisms excrete ammonia as their primary nitrogenous waste.
- These are typically aquatic animals because ammonia is highly toxic and requires a large amount of water for its dilution and excretion.

3. **Identify Ureotelic Organisms**:
- Ureotelic organisms excrete urea.
- This group includes terrestrial animals and some amphibians, such as humans and frogs, which can tolerate moderate toxicity and require a moderate amount of water for excretion.

4. **Identify Uricotelic Organisms**:
- Uricotelic organisms excrete uric acid.
- These animals, such as birds (e.g., pigeons), reptiles (e.g., lizards), and certain insects (e.g., cockroaches), produce uric acid, which is less toxic and requires the least amount of water for excretion.

5. **Categorize the Animals**:
- Based on the above classifications:
- **Ammonotelic**: Aquatic animals (e.g., fish).
- **Ureotelic**: Humans, frogs, and certain amphibians.
- **Uricotelic**: Birds (e.g., pigeons), reptiles (e.g., lizards), and insects (e.g., cockroaches).

6. **Select the Correct Option**:
- After analyzing the options provided in the question, the correct categorization of animals according to the type of nitrogenous waste they excrete is found in option C.

### Final Answer:
The correct option that categorizes animals according to the type of nitrogenous waste they excrete is **Option C**.
