The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion**: The assertion states that transgenic plants that possess the virus coat protein gene exhibit resistance to that specific virus and related varieties. This is a well-established fact in biotechnology, where genetic engineering is used to enhance disease resistance in plants. 2. **Understanding the Reason**: The reason provided explains that the coat protein gene interferes with the uncoating of viruses inside the plant cells. Uncoating is a critical step in the viral life cycle, as it allows the viral genome to be released and replicated within the host cell. 3. **Linking Assertion and Reason**: The assertion and reason are connected. The presence of the coat protein gene in transgenic plants leads to the production of coat proteins that can bind to the virus, preventing it from uncoating. This blockage effectively stops the viral replication process, thereby providing resistance to the plant. 4. **Examples of Transgenic Plants**: The transcript mentions examples of transgenic plants such as tobacco, tomato, alfalfa, sugar beet, and potato, which have been engineered to express the coat protein gene of viruses like the Tobacco Mosaic Virus (TMV). This highlights the practical application of the assertion. 5. **Conclusion**: Both the assertion and reason are correct, and the reason provides a valid explanation for the assertion. Therefore, the correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion. **Final Answer**: Both the assertion and reason are correct, and the reason is the correct explanation of the assertion. ---
