Which of the following groups includes Endothermic animals (Homothermal) :-

Options

A. Crocodile, alligator, turtle
B. Whale, pigeon, bat
C. Sea-horse, dog fish , cat fish
D. Toad , frog, salamander

Answer

To determine which group includes endothermic animals (homothermal), we need to analyze the provided options based on the characteristics of endothermic animals.

### Step-by-Step Solution:

1. **Understanding Endothermic Animals**:
- Endothermic animals, also known as homothermal animals, are those that can maintain a stable internal body temperature regardless of external environmental conditions. This includes mammals and birds.

2. **Analyzing the Options**:
- **Option 1**: Crocodile, Alligator, and Turtle
- These animals are known as ectothermic or cold-blooded. They rely on external sources to regulate their body temperature. Therefore, this option does not include endothermic animals.

- **Option 2**: Whale, Pheasant, and Bat
- All these animals are warm-blooded. Whales (mammals), pheasants (birds), and bats (mammals) can regulate their body temperature internally. This option includes endothermic animals and is the correct answer.

- **Option 3**: Seahorse, Dogfish, and Catfish
- These are all cold-blooded animals (ectothermic). They cannot maintain a stable internal body temperature independently of their environment. Therefore, this option does not include endothermic animals.

- **Option 4**: Toad, Frog, and Salamander
- These are also cold-blooded animals. They are amphibians and rely on the environment to regulate their body temperature. Thus, this option does not include endothermic animals.

3. **Conclusion**:
- The only group that includes endothermic animals is **Option 2: Whale, Pheasant, and Bat**.

### Final Answer:
**The correct answer is Option 2: Whale, Pheasant, and Bat.**
