C. diversity of ecosystems
D. all the three

Answer

**Step-by-Step Solution:**

1. **Understanding Biodiversity**: Biodiversity refers to the variety of life on Earth. It encompasses all living organisms, including plants, animals, fungi, and microorganisms.

2. **Levels of Biodiversity**: Biodiversity can be measured at three main levels:
- **Genetic Diversity**: This refers to the variation in genetic makeup among individuals within a species.
- **Species Diversity**: This involves the variety of species within a particular region or ecosystem.
- **Ecosystem Diversity**: This pertains to the variety of ecosystems in a given place, including different habitats and ecological processes.

3. **Identifying the Correct Level**: The question asks for the level at which biodiversity is defined. Since biodiversity includes variations at the genetic, species, and ecosystem levels, it is essential to recognize that it encompasses all these aspects.

4. **Conclusion**: Therefore, the correct answer is that biodiversity is the variation of life at the levels of genetic diversity, species diversity, and ecosystem diversity.

**Final Answer**: Biodiversity is the variation of life at the levels of genetic, species, and ecosystem diversity.
