Which is artificial manmade fiber?
Correct answer: C. Rayon
- A. Boron
- B. Saffron
- C. Rayon
- D. None of these
Explanation
Rayon is a regenerated cellulose fibre made by chemically processing natural cellulose, so it is classified as a man-made or artificial fibre. Boron is an element and saffron is a natural plant product, so neither is a fibre. Students may choose none of these if they assume an artificial fibre must be completely synthetic rather than regenerated from cellulose.

About Polymers
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
