Which of the following statements is not true?A Clothes are made from fibres,B Selective breeding is not used for woolproductionC Polyester is not a natural fibre,D) Silk fibre is obtained from silk worms,​

Answer ::

B is False (not true) because'Selective Breeding' or 'Artificial Selection'is used for Wool Production.
Two sheeps that yield High-Quantity and High-Quality Wool are breeded together. The offspring that results, produces High-Quality Wool in High-Quantity, which is required by the Woollen Industry.

Clothes are made from natural fibres like Cotton, Hemp, Jute, etc...
Polyester is a man-made Fibre made up of a Functional group called 'Ester.' Poly-ester means'many esters linked together.'This fibre does not contain pores like Natural Fibres and hence They are not Comfortable like Natural Fibres.
Silk Fibre is obtained from Silk Worms. Best known Silk is obtained byMulberry Silkwormsand their cultivation is called'Seri-Culture.'
