Jute is a long, soft, shiny vegetable fiber, that can be spun into coarse, strong threads. It is produced from plants in the genus Corchorus, which was once classified with the family Malvaceae. Jute is one of the most affordable natural fibers and is second only to cotton in amount produced and variety of uses of vegetable fibers. Jute fibers are composed primarily of the plant materials cellulose and lignin. It falls into the bast fiber category (fiber collected from bast or skin of the plant or secondary phloem) along with kenaf, industrial hemp, flax (linen), ramie, etc. Thus, option B is correct.
