Options

A. Colder regions of world
B. Warmer regions of world
C. Antarctica
D. Oceans

Answer

**Step-by-Step Solution:**

1. **Understanding Gymnosperms and Angiosperms**:
- Gymnosperms are seed-producing plants that do not form flowers or fruits. They include conifers, cycads, and ginkgo.
- Angiosperms are flowering plants that produce seeds enclosed within a fruit.

2. **Historical Context**:
- Gymnosperms are considered more ancient than angiosperms. They were the dominant plant group before angiosperms evolved around 200 million years ago.

3. **Environmental Adaptations**:
- Gymnosperms have adapted to various climates, but they are particularly well-suited to certain environments.
- They thrive in colder regions where conditions may not be favorable for angiosperms.

4. **Water Sources**:
- In colder regions, the primary source of water is often snow rather than rainfall. This allows gymnosperms to survive and dominate in these areas.

5. **Current Dominance**:
- Today, gymnosperms maintain their dominance primarily in colder regions of the world, where they can outcompete angiosperms due to their adaptations to the environment.

6. **Conclusion**:
- Therefore, the correct answer to the question is that gymnosperms maintain their dominance over angiosperms in colder regions.

**Final Answer**: Colder regions of the world.
