Question

Fibre crops include :
A) Cotton
B) Jute
C) Flax
D) All of these

Answer 1

Hint: 1)Fibre crops or plant fibres are often referred to as natural fibres because they are derived directly and naturally from various plant sources and their products.
2)Fiber crops are plants that are purposely grown for textile fibre processing, cordage and filing

Complete answer:
Fibre crops or plant fibres are often referred to as natural fibres because they are derived directly and naturally from various plant sources and their products.
Fibres are the cells of sclerenchyma that are attached to the vascular tissues and are a part of the skeleton of plants. With pointed ends, the cells are long. They are the raw materials that are rendered into fabrics in the form of thin, long continuous threads and flexible strands spun into yarn.

Natural fibres were used in the manufacture of fabric, paper, ropes, etc., prior to the advent of synthetic fibres. The fibre crops in the processing industries were the origins of these natural fibres. Due to the presence of cellulose, these fibres are very solid.

Lets see options :
Cotton : Cotton is the fibre of the plant obtained from the cotton plant. It is a tropical plant cultivated predominantly in regions with black soil and warm conditions thus this option is correct.
Jute : Jute is a fibre that is long, smooth, shiny and obtained from vegetables. It is the most economical and has a range of applications for natural fibres thus this option is correct too.
Flax : Flax, which is also known as linseed or common flax seeds. To make handkerchiefs, ropes, and high-quality documents, the fibres extracted from these plants are used thus this option is correct too.
All of these : above all options are correct too thus this option is the right answer.

Hence, the correct answer is option (D).

Note: The first fabrics to be obtained were plant source fabrics and were about 100,000 years old. Flax fibres were the first fabrics to be used for the manufacture of various textile products, later followed by cotton, jute, etc., among all plant fibre sources.
In addition to these, other plants are often used to manufacture ropes, garments, and other clothing products, including palm, rush, reed, and papyrus plants, along with flax.
