D. Birds

Answer

To solve the question "Which one is a group of warm-blooded animals?" we need to analyze the options provided:

1. **Understanding Warm-Blooded Animals**:
- Warm-blooded animals, also known as endothermic animals, have the ability to maintain a constant internal body temperature regardless of external environmental conditions. This means that their body temperature remains relatively stable even when the temperature around them fluctuates.

2. **Evaluating the Options**:
- **(a) Fishes**: Fishes are generally cold-blooded (ectothermic), meaning their body temperature varies with the temperature of their environment.
- **(b) Amphibians**: Amphibians, like frogs and salamanders, are also cold-blooded and cannot regulate their body temperature independently of their environment.
- **(c) Reptiles**: Reptiles, such as snakes and lizards, are cold-blooded as well, relying on external heat sources to regulate their body temperature.
- **(d) Birds**: Birds are warm-blooded animals. They can maintain a constant internal body temperature, which allows them to thrive in various environments.

3. **Conclusion**:
- Based on the definitions and characteristics of the groups listed, the correct answer is **(d) Birds**. Birds are the only group among the options provided that are classified as warm-blooded animals.

**Final Answer**: (d) Birds
