The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Rayon**: - Rayon is a type of fiber that is known for its silk-like feel and appearance. It is important to recognize that rayon is not a natural fiber but a manmade one. 2. **Composition of Rayon**: - Rayon is primarily made from purified cellulose. Cellulose is a natural polymer found in the cell walls of plants, and in the case of rayon, it is usually derived from wood pulp. 3. **Production Process**: - The production of rayon involves several chemical processes: - First, cellulose is extracted from wood pulp. - The cellulose is then treated with sodium hydroxide (NaOH) to create a viscous solution. - This viscous solution is referred to as "viscose," which is a syrup-like liquid. 4. **Spinning Process**: - The viscose is then forced through a spinneret, which is a device with many tiny holes, to form long threads. - These threads are then treated with diluted sulfuric acid (H2SO4), which helps in regenerating the cellulose and solidifying the fibers. 5. **Final Product**: - After the spinning and treatment, the final product is rayon, which is often referred to as "artificial silk" due to its similar texture and appearance to natural silk. 6. **Conclusion**: - Based on the above information, we can conclude that rayon is correctly classified as "artificial silk." ### Final Answer: - Rayon is correctly identified as **artificial silk**.
