Answer

To solve the question regarding the correct categorization of excretory processes, we will follow these steps:

### Step 1: Understand the Types of Excretory Processes
We need to categorize organisms based on the type of waste they excrete. The three main types are:
- **Ammonotelic**: Excrete ammonia.
- **Ureotelic**: Excrete urea.
- **Uricotelic**: Excrete uric acid.

### Step 2: Analyze Ammonotelic Organisms
Ammonotelic organisms excrete ammonia, which is highly toxic and requires a lot of water for dilution. These organisms are typically aquatic since they need a large water environment to excrete ammonia effectively. Examples include:
- Aquatic animals like fish.

### Step 3: Analyze Ureotelic Organisms
Ureotelic organisms excrete urea, which is less toxic than ammonia and requires moderate amounts of water for excretion. This process occurs in the liver through the urea cycle. Examples include:
- Humans
- Frogs

### Step 4: Analyze Uricotelic Organisms
Uricotelic organisms excrete uric acid, which is the least toxic and requires minimal water for excretion. This adaptation helps conserve water. Examples include:
- Reptiles (like lizards)
- Birds (like pigeons)
- Insects (like cockroaches)

### Step 5: Match Examples with Categories
Now we need to match the organisms given in the options with their respective categories:
- **Ammonotelic**: Typically aquatic organisms (e.g., fish).
- **Ureotelic**: Humans and frogs.
- **Uricotelic**: Reptiles, birds, and insects.

### Step 6: Evaluate the Options
Based on the analysis:
1. **Option 1**: Incorrect (includes terrestrial animals that cannot excrete ammonia).
2. **Option 2**: Likely correct (includes ureotelic organisms).
3. **Option 3**: Incorrect (cockroach is uricotelic, not ureotelic).
4. **Option 4**: Incorrect (includes terrestrial animals that cannot excrete ammonia).

### Conclusion
The correct categorization is found in **Option 2**, which includes ureotelic organisms like humans and frogs.
