Which of the following fibre is obtained by flax seeds?(A) Silk.(B) Cotton.(C) Linen. (D) Polyester.

The correct answer is (C) Linen.

Explanation:
Flax Seeds: Flax (Linum usitatissimum) is a plant cultivated for its seeds and fibers. The fibers extracted from the stem of the flax plant are used to make linen.

Linen: This is a textile made from the fibers of the flax plant. Linen is known for its strength, durability, and breathable properties, making it a popular choice for clothing, bed linens, and other household textiles.

Other Options:

(A) Silk: This is a natural fiber obtained from the cocoons of silkworms, particularly the Bombyx mori.
(B) Cotton: This fiber comes from the cotton plant's bolls, which are the protective capsules around the seeds.
(D) Polyester: This is a synthetic fiber made from petroleum-based products, not derived from natural sources like flax.
Thus, flax seeds specifically lead to the production of linen fiber.
