Options

A. Beak with teeth
B. Absence of pygostyle
C. Distinct digits in wings and claws on its fingers
D. All the above

Answer

To answer the question regarding the reptilian character present in Archaeopteryx, we will analyze the options provided and identify the characteristics that link Archaeopteryx to reptiles.

### Step-by-Step Solution:

1. **Understanding Archaeopteryx**:
- Archaeopteryx is considered a transitional fossil that exhibits features of both birds and reptiles. It is often referred to as a "connecting link" between these two groups.

2. **Analyzing the Options**:
- We have four options to consider:
a. Beak with teeth
b. Absence of pygostyle
c. Distinct digits in wings and claws on its fingers
d. All of the above

3. **Identifying Reptilian Characters**:
- **Beak with Teeth**:
- Unlike modern birds, which have toothless beaks, Archaeopteryx had a beak that contained teeth, a characteristic feature of reptiles.
- **Absence of Pygostyle**:
- The pygostyle is a fused bone found in modern birds that supports tail feathers. Archaeopteryx lacked this structure, which is more similar to reptiles.
- **Distinct Digits in Wings and Claws on Fingers**:
- Archaeopteryx had clawed digits, which are more reptilian in nature. The presence of claws on its fingers indicates a connection to reptilian ancestry.

4. **Conclusion**:
- Since all the options provided (beak with teeth, absence of pygostyle, distinct digits in wings, and claws on fingers) are characteristics that link Archaeopteryx to reptiles, the correct answer is:
- **D. All of the above**.

### Final Answer:
The reptilian character present in Archaeopteryx is **D. All of the above**.
