Answer

To determine which nature bounty is used for giving protection to fauna only, we need to analyze the options provided and understand the concepts of biodiversity conservation.

### Step-by-Step Solution:

1. **Understanding Fauna and Flora**:
- Fauna refers to the animal life in a particular region, while flora refers to the plant life. In this question, we are specifically interested in the protection of fauna.

2. **Conservation Methods**:
- There are two main methods of conserving biodiversity:
- **In-situ Conservation**: This method involves protecting species in their natural habitats. Examples include national parks, biosphere reserves, and wildlife sanctuaries.
- **Ex-situ Conservation**: This method involves protecting species outside their natural habitats, such as in botanical gardens or zoos.

3. **Analyzing the Options**:
- **Option A: Botanical Garden**: This is an example of ex-situ conservation and is primarily focused on conserving plant species, not fauna.
- **Option B: National Park**: This is an in-situ conservation area that protects both flora and fauna.
- **Option C: Biosphere Reserve**: Similar to national parks, biosphere reserves protect both plants and animals.
- **Option D: Wildlife Sanctuary**: This is specifically designed for the protection of wildlife (fauna) in their natural habitat.

4. **Conclusion**:
- Among the options provided, the Wildlife Sanctuary (Option D) is the only nature bounty that focuses exclusively on the protection of fauna.

### Final Answer:
The correct answer is **D: Wildlife Sanctuary**.
