C. Both (1) & (2)
D. None

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Biosphere**: The biosphere is the global sum of all ecosystems. It is the zone of life on Earth, a closed system, and largely self-regulating. It includes all living organisms and their interactions with the environment.

2. **Components of the Biosphere**: The biosphere is influenced by three main components: land (lithosphere), air (atmosphere), and water (hydrosphere). These components interact with each other and with living organisms.

3. **Categories of the Biosphere**: The biosphere can be categorized based on the environments in which organisms live. The two basic categories are:
- **Terrestrial**: This category includes all ecosystems found on land. It encompasses various habitats such as forests, deserts, grasslands, and tundras.
- **Aquatic**: This category includes all ecosystems found in water. It includes freshwater ecosystems (like rivers and lakes) and marine ecosystems (like oceans and coral reefs).

4. **Conclusion**: Therefore, the two basic categories of the biosphere are:
- Terrestrial
- Aquatic

5. **Correct Answer**: The correct option is (C) both one and two, which indicates that both terrestrial and aquatic are the two basic categories of the biosphere.
