The correct option is B False
All cloth materials are made up of long, narrow, thin structures called fibres. Fibres are obtained from natural as well as man-made sources.
Natural fibres like cotton, jute, silk, wool, etc. and man- made materials like polyester, nylon, rayon, etc. are used for making clothes.
All fibres are not suitable for making cloth. Coir fibres, for instance, are very hard and can only be used for making ropes or in mattresses.
