The correct answer is option 2 - Cotton, Jute, Silk, Wool.
These 4 products are obtained naturally from plants and animals. Therefore, they are said to contain only natural fibres.
1. Cotton - is a soft, fluffy staple fibre that grows in a boll, or protective case, around the seeds of the cotton plant.
2. Jute - Jute is a long, soft, shiny vegetable fibre that is produced primarily from plants in the genus Corchorus. It is spun into long threads and used for making gunny cloth, burlap etc.
3. Silk - Silk is a natural protein fibre that is composed mainly of fibroin and is produced by the insect larvae of the silk-worm to form cocoons. Most forms of silk are used to be woven into textiles.
4. Wool - Wool is the textile fibre obtained from sheep and other animals. They are made from the animal fibre that forms the protective covering, or fleece, of sheep or of other hairy mammals, such as goats and camels.
