Which of the following fibers is man-made and often confused with natural fibers?

Rayon is a man-made fiber derived from natural sources such as wood pulp. It undergoes a chemical process that transforms the cellulose from the pulp into a fiber that can be woven and utilized in textiles. Because it is made from natural materials, rayon can often be confused with fibers like cotton and linen, which are completely natural. In terms of texture and appearance, rayon mimics these natural fibers closely, making it difficult to distinguish between them without further testing.

Cotton and linen are both entirely natural, plant-based fibers, while hemp is another natural fiber derived from the hemp plant. Since the question specifically inquires about man-made fibers, rayon is the accurate answer, due to its synthetic processing and similarity to natural fibers in characteristics and usability.
