Answer

**Step-by-Step Solution:**

1. **Understanding Archaeopteryx**: Archaeopteryx is a significant fossil that exhibits characteristics of both birds and reptiles. It is often referred to as a "missing link" or "connecting link" in evolutionary biology.

2. **Identifying the Characteristics**:
- **Reptilian Characteristics**: Archaeopteryx has several features that are typical of reptiles. These include:
- A long lizard-like tail
- Pre-caudal vertebrae
- Non-pneumatic bones (bones that are not hollow)

- **Avian Characteristics**: It also displays features associated with birds, such as:
- Feathers on its body
- Jaws modified into a beak
- Forelimbs modified into wings
- Hindlimbs structured in a way that is typical for birds

3. **Determining the Correct Link**: Given that Archaeopteryx exhibits both reptilian and avian characteristics, it serves as a crucial link in understanding the evolution of birds from reptiles.

4. **Choosing the Correct Option**: From the options provided:
- Option A: Fishes and amphibians - Incorrect
- Option B: Birds and reptiles - Correct
- Option C: Reptiles and mammals - Incorrect
- Option D: Caudates and non-caudates - Incorrect

5. **Conclusion**: The correct answer is Option B: Archaeopteryx is a connecting link between birds and reptiles.
