The best method to preserve the wild relatives of plants is

Options

A. By growing them in natural habitats
B. Gene library
C. By storing seeds
D. Cryopreservation

Answer

To solve the question about the best method to preserve the wild relatives of plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the best method to preserve wild relatives of plants. This indicates that we need to consider methods that maintain the natural characteristics and genetic diversity of these plants.

2. **Evaluate the Options**:
- **Growing them in natural habitats**: This method allows plants to thrive in their native environments, which is crucial for their survival and preservation.
- **Gene library**: This involves storing genetic sequences, which is more about data collection than actual preservation of living plants.
- **Storing seeds**: While this method can preserve certain plant species, it does not specifically cater to the unique needs of wild relatives.
- **Cryopreservation**: This technique involves freezing plant material at very low temperatures, which may not allow for the natural growth and adaptation of wild relatives.

3. **Analyze the Best Method**:
- The most effective way to preserve wild relatives of plants is by growing them in their natural habitats. This ensures that they can interact with their ecosystem, adapt to environmental changes, and maintain their genetic diversity.

4. **Conclusion**: Based on the analysis, the best method to preserve wild relatives of plants is by growing them in natural habitats.

### Final Answer:
The best method to preserve the wild relatives of plants is by **growing them in natural habitats**.
