Angiosperms evolved during

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Angiosperms**: Angiosperms are flowering plants that produce seeds enclosed within a fruit. This characteristic distinguishes them from other plant groups.

2. **Identifying the Era**: The question asks when angiosperms evolved. To answer this, we need to look at the geological time scale and identify the relevant periods.

3. **Triassic Period**: The Triassic period, which occurred approximately 250 to 200 million years ago, is known for the evolution of dinosaurs and the first true mammals. However, angiosperms did not evolve during this period.

4. **Jurassic Period**: Following the Triassic, the Jurassic period (approximately 200 to 145 million years ago) saw significant evolutionary developments, particularly in dinosaurs and early land plants. However, angiosperms were still not present during this time.

5. **Cretaceous Period**: The Cretaceous period (approximately 145 to 66 million years ago) is crucial for the evolution of angiosperms. It is during the Late Cretaceous (around 100 to 125 million years ago) that angiosperms first appeared. This period is characterized by the development of flowers and fruits, which helped in attracting pollinators and protecting seeds.

6. **Conclusion**: Based on the information gathered, the correct answer to the question of when angiosperms evolved is during the **Cretaceous period**.

**Final Answer**: Angiosperms evolved during the Cretaceous period.
