The correct Answer is:
To solve the given question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that "Rayon is a semisynthetic polymer and is taken as a better choice than cotton fabric." - Rayon is derived from natural cellulose, which is chemically modified to produce the fiber. This makes it a semisynthetic polymer because it combines natural and synthetic processes. - The statement that rayon is a better choice than cotton can be justified by its properties such as softness, drape, and moisture absorption. 2. **Understanding the Reason (R)**: - The reason states that "Mechanical and aesthetic properties of cellulose can be improved by acetylation." - Acetylation is a chemical reaction where an acetyl group is introduced into a compound. In the case of cellulose, acetylation enhances its properties, making it more suitable for fiber production. - This means that the mechanical strength and aesthetic appeal of cellulose can indeed be improved through this process. 3. **Evaluating the Relationship**: - Both the assertion and reason are true statements. - The reason provides a valid explanation for the assertion. The improvement in properties due to acetylation is what makes rayon a better choice compared to cotton. 4. **Conclusion**: - Since both the assertion and the reason are true, and the reason correctly explains the assertion, we conclude that the correct answer is that both are true and the reason is the correct explanation of the assertion. ### Final Answer: Both assertion and reason are true, and the reason is the correct explanation of the assertion.
