Question

Animal fibre is

• A. Hemp
• B. Flax
• C. Silk
• D. Jute

Hint:

Silk is the most well-known animal fiber, harvested from the larvae of silkworms.

Answer 1

The Correct Option is C

Step 1: Understanding animal fibers.
Animal fibers are derived from animals and include materials like silk and wool. These fibers are different from plant fibers like hemp and flax. Silk, for instance, comes from the silkworm.
Step 2: Analyzing the options.
(A) Hemp: This is a plant fiber, not an animal fiber.
(B) Flax: This is also a plant fiber, typically used to make linen.
(C) Silk: Correct — Silk is an animal fiber produced by silkworms.
(D) Jute: This is another plant fiber, not an animal fiber.
Step 3: Conclusion.
The correct answer is (C) Silk, as it is an animal fiber.

Answer 2

The quickest way to sort these four fibres is by their biological origin, animal versus plant.

1. Hemp: Hemp fibre is obtained from the stem (bast fibre) of the Cannabis sativa plant, making it a plant fibre.
2. Flax: Flax fibre, used to make linen, likewise comes from the stem of the flax plant (Linum usitatissimum), another plant fibre.
3. Silk: Silk fibre is spun by the silkworm larva (Bombyx mori) to build its cocoon, and is composed of the protein fibroin, an animal secretion rather than any plant material.
4. Jute: Jute fibre comes from the stem of the jute plant (Corchorus species), again a plant fibre, commonly used for sacking and rope.

Of the four, silk is the only one produced by an animal (the silkworm) rather than extracted from a plant stem.

Therefore, the correct answer is Silk.
