Assertion: Virus-free plants can be produced from virus infected plants by means of meristem tissue culture,
Reason: The virus fails to grow during the growth of host tissue in the artificial medium.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the Reason is not the correct explanation of the assertion
C. If assertion is true but the Reason are false
D. If both Assertion and Reason are false

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that virus-free plants can be produced from virus-infected plants using meristem tissue culture. This is a well-known technique in plant biotechnology. The meristematic tissues (apical and axillary meristems) are usually free from viruses, allowing for the production of healthy plants.

2. **Understanding the Reason**: The reason provided is that the virus fails to grow during the growth of host tissue in an artificial medium. This statement is misleading. While it is true that meristematic tissues can be used to produce virus-free plants, the reason given does not accurately explain why this is possible.

3. **Analyzing the Meristematic Tissue**: In meristem tissue culture, the apical and axillary meristems are isolated from the infected plant. These tissues are typically free from viruses because they are not fully differentiated and are less likely to harbor viral infections compared to other plant tissues.

4. **Evaluating the Virus Growth**: The reason states that the virus fails to grow in the artificial medium. However, viruses require living host cells to replicate and produce new viral particles. Therefore, the assertion that the virus fails to grow in the artificial medium is incorrect because the virus can grow in the host plant's cells.

5. **Conclusion**: Based on the analysis, the assertion is true (virus-free plants can be produced from virus-infected plants through meristem tissue culture), but the reason is false (the virus does not fail to grow in host tissue). Therefore, the correct answer is that the assertion is true, and the reason is false.

**Final Answer**: Assertion is true, Reason is false. (Option C)
