B. Cotton
C. Rayon
D. Polyester

Answer 1

Hint: Polyester is a synthetic polymer that is obtained from coal, petroleum, air, and water. It is made up of polymers that contain the ester functional group in their main chain and involve chemical reactions. In silk, the protein fiber is composed of fibroin and is produced from certain insect larvae to form cocoons.

Complete answer: Cotton is a natural, soft fiber that grows with seeds of the cotton plant. It can be spun into cotton threads after the fiber is collected from the plants. It grows well in both tropical and subtropical regions of the world.
The fiber is spun into yarn or thread and is used to make a soft, breathable textile, these include bath towels and robes; denim for blue jeans, etc.
It is a pure fiber that is obtained from plants and is used widely.
Rayon is an artificial textile material that is composed of regenerated cellulose fiber, obtained from natural sources of cellulose like wood, etc.
It is produced from cocoons of Bombyx mori insects.

Hence, the correct option is (B) Cotton

Note: Organic cotton is not genetically modified and that is certified to be grown without the use of any synthetic agricultural chemicals, such as fertilizers or pesticides.
Its production also promotes and enhances biodiversity and biological cycles.
