The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that "disarmed Ti plasmid can be utilized as a shuttle vector." A shuttle vector is a DNA molecule that can replicate in multiple host organisms, typically both prokaryotic (like bacteria) and eukaryotic (like plants or yeast). 2. **Understanding the Reason**: The reason given is that "it can survive in both prokaryotic and eukaryotic organisms." This means that the disarmed Ti plasmid is capable of existing and functioning in different types of cells, which is a key characteristic of shuttle vectors. 3. **Evaluating the Assertion**: The disarmed Ti plasmid is indeed used as a shuttle vector. It can replicate in Agrobacterium tumefaciens (a prokaryote) and can also be transferred into eukaryotic cells, such as plant cells. Therefore, the assertion is true. 4. **Evaluating the Reason**: The reason provided is also true. The disarmed Ti plasmid can survive in both prokaryotic and eukaryotic organisms, which supports its use as a shuttle vector. 5. **Conclusion**: Since both the assertion and the reason are true, and the reason correctly explains why the assertion is true, the final 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 true, and the reason is the correct explanation of the assertion. ---
