D. All the above

Answer 1

Hint: The thin strands of thread are known as fibre. The fibres are classified as natural fibres and synthetic fibres. The fibres obtained from plant and animal sources are known as natural fibre. Such as cotton, jute is obtained from plants and wool, silk is obtained from animal sheep and silkworm respectively.

Complete answer: Seed fibres: the plant fibres that are obtained from the seeds of the plant are called plant fibres, e.g. cotton. Cotton belongs to the genus Gossipier in the family of Malvaceae. They represent the purest natural cellulose form containing 90% of this as polysaccharides. It has a good absorbency; colour retention property. It is used in the textile and pharma industry.
Bast fibres - the plant fibres collected from the inner bark or blast of plants are called bast fibres. E.g. jute, flax, hemp, etc. Flax is naturally cultivated in colder regions. These fibres are stronger than cotton fibres. They are smooth and straight. It is used in the textile industry, surgical threads, etc.
Hemp fibres are fibres used in making ropes, shoes, biofuels, etc.
Hard fibres: the plant fibres obtained from the leaves of the plants. E.g. coir from the hard shell of coconuts.
So, the correct answer is option D.

Note: Any fabric is made up of yarns are arranged together; yarns are made of thin threads called fibre. The fibres are man made i.e. they are obtained from chemical substances are called synthetic fibres, such as polyester, rayon, nylon, etc.
