Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Artificial selection is highly beneficial for humans." This means that artificial selection, which involves humans selectively breeding organisms for desired traits, has positive impacts on human needs.

2. **Understanding the Reason**: The reason provided is "Artificial selection is carried out by man." This indicates that humans are the ones who perform artificial selection, making choices about which organisms to breed based on specific characteristics.

3. **Evaluating the Assertion**:
- Artificial selection is indeed beneficial for humans. It allows for the development of new breeds of plants and animals that have desirable traits, such as higher yields in crops or specific characteristics in livestock.
- This process can lead to improved food production, disease resistance, and other advantageous traits that can enhance human life.

4. **Evaluating the Reason**:
- The reason is also correct; artificial selection is performed by humans. It is a deliberate process where humans select which organisms to breed based on their traits.
- However, while the reason is true, it does not explain why artificial selection is beneficial. It merely states who performs the process.

5. **Conclusion**:
- Both the assertion and the reason are true statements. However, the reason does not adequately explain the assertion. Therefore, the assertion is correct, the reason is correct, but the reason is not the correct explanation for the assertion.

### Final Answer:
- **Assertion**: True
- **Reason**: True
- **Explanation**: The reason is not the correct explanation of the assertion.
