Options

A. National park
B. Sanctuary
C. Botanical garden
D. Biosphere reserve

Answer

### Step-by-Step Solution:

1. **Understand In Situ Conservation**: In situ conservation refers to the conservation of species in their natural habitats. This includes protecting endangered species of plants, animals, and other organisms where they naturally occur.

2. **Identify Examples of In Situ Conservation**: Common examples of in situ conservation include:
- National Parks
- Wildlife Sanctuaries
- Biosphere Reserves

3. **Analyze the Options Given**: The question provides four options:
- National Park
- Sanctuary
- Botanical Garden
- Biosphere Reserve

4. **Determine Which Option is Not In Situ**:
- National Parks, Sanctuaries, and Biosphere Reserves are all designed to protect species in their natural habitats, thus they are part of in situ conservation.
- A Botanical Garden, however, is a place where plants are cultivated for study, display, and conservation outside their natural habitats. Therefore, it falls under ex situ conservation.

5. **Conclude the Answer**: Based on the analysis, the option that is not included under in situ conservation is the **Botanical Garden**.

### Final Answer:
**Botanical Garden** is not included under in situ conservation.
