Hint:Jute is a raw fibre used as a gunny bag, curtains, bags, etc. The capsules of Corchorus belonging to the Tiliaceae family are collected, isolated from the secondary phloem of the plantation. The fibres are grouped into two xylem fibres, also called the wood fibres. They are the longest part of the plant.
Complete answer:The fibre of the plant (the "inner bark") or bast is a fibre from the plant that covers the trunk of some plants, primarily dicotyledons. They assist and reinforce the conductive cells of the phloem. Cellulosic fibre from phloem or outer bark of the plant, kenaf, flax, and hemp, are solid natural bast fibre. Fibres jute was pretty much fibre (phloem fibres).
These fibres, also known as wood fibres, comprise two xylem fibres, the longer xylem fibre the more significant and the non-significant. The extra xylem fibres are categorised as flower fibres, cortical fibres and perivascular fibres. The body of the plant will resist different strains based on the elasticity of the fibres. The industrial jute, ramie and flax fibres are all extra xylem fibres. The jute fibres consist mainly of lignin and cellulose. It is known as Bast Fibers obtained from the plant skin or the secondary phloem.
Option C: Phloem fibers are therefore right.
Note: For the following reasons, Jute is an excellent material for the production of shopping bags: the raw material is environmentally friendly, visually pleasing, and jute fibre can be harvested very fast. Jute is grown in India and in Bangladesh from the tree of the capillary finch. In tapestry, interior decoration and industrial areas, this especially durable plant fibre is often used. It is cut into strips and weaved with a web after harvesting the jute. Those textiles are then assembled to create jute bags. Usually, the jute bag is beige but it can be dyed as the customer wishes.
