(D) Wool, Cotton, Silk, Jute, Nylon
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (C)
Natural fibres come from plants or animals; synthetic fibres are made in factories from chemicals (mostly from petroleum). Wool, cotton, silk and jute are natural in every set, so each set is decided by its fifth fibre.
(A) Wool, Cotton, Silk, Jute, Polyester Incorrect. Polyester is a synthetic fibre, made from chemicals; terylene and PET are forms of it.
(B) Wool, Cotton, Silk, Jute, Acrylic Incorrect. Acrylic is a synthetic fibre, used as a cheaper substitute for wool in sweaters and shawls.
(C) Wool, Cotton, Silk, Jute, Dhaincha Correct. Dhaincha (Sesbania) is a plant grown as green manure whose stalks also yield a bast fibre, like jute, so all five fibres are natural.
(D) Wool, Cotton, Silk, Jute, Nylon Incorrect. Nylon was the first fully synthetic fibre, made from coal, water and air.
