One of the most important reason why wild plants should thrive is that these are good source of

Options

A. unsaturated edible oils
B. highly nutritive animals feed
C. genes for resistance to disease and pests
D. rare and highly sought after fruits of medical importance

Answer

To answer the question, "One of the most important reasons why wild plants should thrive is that these are a good source of," we need to analyze the given options and determine which one aligns best with the significance of wild plants.

### Step-by-Step Solution:

1. **Understand the Importance of Wild Plants**:
- Wild plants play a crucial role in biodiversity and ecosystems. They are essential for maintaining ecological balance and provide various resources.

2. **Examine the Options**:
- We have four options to consider:
1. Unsaturated edible oils
2. Highly nutritive animal feed
3. Gene for resistance to disease and pest
4. Rare and highly sought-after fruits of medical importance

3. **Evaluate Each Option**:
- **Option 1: Unsaturated edible oils** - While some wild plants may produce edible oils, this is not the primary reason for their importance.
- **Option 2: Highly nutritive animal feed** - Wild plants can contribute to animal feed, but this is not the most significant aspect of their value.
- **Option 3: Gene for resistance to disease and pest** - Wild plants are indeed a reservoir of genetic diversity, including genes that confer resistance to diseases and pests. This genetic resource is vital for crop improvement and sustainability.
- **Option 4: Rare and highly sought-after fruits of medical importance** - Although some wild plants produce valuable fruits, this is not as broadly applicable as the genetic diversity they offer.

4. **Identify the Correct Answer**:
- After evaluating the options, **Option 3: Gene for resistance to disease and pest** is the most appropriate answer. Wild plants are crucial for their genetic resources, which can be used to enhance crop resilience and food security.

5. **Conclusion**:
- Therefore, the most important reason why wild plants should thrive is that they are a good source of genes for resistance to disease and pests.

### Final Answer:
**The correct answer is: Gene for resistance to disease and pest.**
