(c) Permian
(d) Jurassic

Options

A. Cretaceous
B. Triassic
C. Permian
D. Jurassic

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks during which geological period Archaeopteryx lived. The options provided are Cretaceous, Triassic, Permian, and Jurassic.

2. **Identifying Archaeopteryx**: Archaeopteryx is recognized as a significant transitional fossil that exhibits characteristics of both dinosaurs and modern birds. This places it in a unique evolutionary context.

3. **Historical Context**: Paleontologists have determined that Archaeopteryx lived approximately 150 million years ago. This timeframe is crucial for identifying the correct geological period.

4. **Geological Periods**:
- The **Cretaceous** period followed the Jurassic and is known for the dominance of dinosaurs and the emergence of flowering plants.
- The **Triassic** period is earlier than the Jurassic and is characterized by the rise of dinosaurs.
- The **Permian** period is even earlier and is known for the diversification of reptiles.
- The **Jurassic** period is known for the flourishing of dinosaurs and the first appearance of birds.

5. **Conclusion**: Based on the information that Archaeopteryx lived around 150 million years ago and is associated with the late Jurassic period, we conclude that the correct answer is (d) Jurassic.

**Final Answer**: (d) Jurassic
