Options

A. ex-situ conservation of biodiversity
B. in-situ conservation of biodiversity
C. collection of different types of soil
D. taxonomical aids

Answer

To solve the question regarding the methods of cryopreservation, seed bank, gene bank, and wildlife safari parks, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Conservation Methods**:
- Conservation methods are primarily categorized into two types: **in-situ conservation** and **ex-situ conservation**.
- **In-situ conservation** involves protecting endangered species in their natural habitats, such as national parks and biosphere reserves.
- **Ex-situ conservation** involves taking endangered species out of their natural habitats and providing them with protection in controlled environments.

2. **Identifying the Methods**:
- **Cryopreservation**: This is a method where biological samples (like seeds or embryos) are preserved at very low temperatures to maintain their viability.
- **Seed Bank**: This is a facility where seeds are stored to preserve genetic diversity and protect against extinction.
- **Gene Bank**: Similar to seed banks, gene banks preserve genetic material, such as DNA, to ensure the survival of species.
- **Wildlife Safari Parks**: These are controlled environments where wildlife is protected and can live in conditions that mimic their natural habitat.

3. **Categorizing the Methods**:
- All the mentioned methods (cryopreservation, seed bank, gene bank, and wildlife safari parks) involve taking species out of their natural habitats to provide them with protection and safety. Therefore, they fall under **ex-situ conservation**.

4. **Final Answer**:
- Based on the definitions and examples provided, the correct answer to the question is:
- **a. ex-situ conservation of biodiversity**.
