Which term describes materials produced by plants or animals that can be spun into a thread, rope or filament?

• A. Non-toxic
• B. Oxidization resistance
• C. Natural fibres
• D. One-off production

Answer: (C)

Natural fibres describe materials produced by plants or animals that can be spun into a thread, rope, or filament. They come from living sources and have a fibrous structure that can be drawn out into long, continuous strands for textiles and cords. Examples include cotton and flax from plants, and wool or silk from animals. This focus on origin and form distinguishes them from terms about safety, chemical resistance, or production scale, which don’t define the material type. While synthetic fibres can also be spun into thread, they aren’t produced by plants or animals, so they aren’t natural fibres.
