Correct Answer: Wool
Solution : The correct answer is Wool.
Wool is a natural fibre made of protein molecules that are obtained from the fleece of sheep or other animals. Microorganisms in the environment can break down these protein molecules over time, causing wool to decompose. Wool's biodegradability makes it a more environmentally friendly choice than synthetic fibres, which can last far longer in the environment. Wool will eventually degrade and return to the natural ecosystem.
