In which of the following both pairs have correct combination ?

Options

A. In situ conservation : Cryopreservation
Ex situ conservation, Wildlife Sanctuary
B. In situ conservation : Seed Bank
Ex situ conservation, National Park
C. In situ conservation : Tissue culture
Ex situ conservation, Sacred groves
D. In situ conservation : National Park
Ex situ conservation, Botanical Garden

Answer

To solve the question, we need to identify which pairs of conservation methods and their corresponding examples are correctly matched. The conservation methods are classified into two categories: in-situ and ex-situ.

### Step-by-Step Solution:

1. **Understand the Types of Conservation**:
- **In-situ Conservation**: This method involves the conservation of species in their natural habitats. Examples include national parks, wildlife sanctuaries, and biosphere reserves.
- **Ex-situ Conservation**: This method involves the conservation of species outside their natural habitats. Examples include zoos, botanical gardens, seed banks, and pollen banks.

2. **Analyze the Given Options**:
- We need to check each pair of conservation method and example to see if they are correctly matched.

3. **Evaluate Each Pair**:
- **Cryopreservation**: This is a technique used in ex-situ conservation, particularly for seed banks. It involves preserving biological material at very low temperatures. Therefore, this pair is correct if matched with ex-situ.
- **In-situ Seed Bank**: This is incorrect because seed banks are a form of ex-situ conservation.
- **In-situ Tissue Culture**: This is also incorrect as tissue culture is typically done in controlled environments outside of natural habitats (ex-situ).
- **National Park (In-situ) and Botanical Garden (Ex-situ)**: This pair is correct. National parks are examples of in-situ conservation, while botanical gardens are examples of ex-situ conservation.

4. **Conclusion**:
- The only correct combination is the one that includes "National Park" as in-situ and "Botanical Garden" as ex-situ.

### Final Answer:
The correct option is: **National Park (In-situ) and Botanical Garden (Ex-situ)**.
