Which of the following fibres is called vegetable fibre?

(a) Cotton

(b) Wool

(c) Jute

(d) None of the above

This question is tricky because "vegetable fibre" is another term for "plant fibre," and both cotton and jute are derived from plants.

• (a) Cotton: This is a vegetable fibre that comes from the seed pod of the cotton plant.
• (b) Wool: This is an animal fibre, not a vegetable fibre.
• (c) Jute: This is a vegetable fibre that comes from the stem of the jute plant.

Since both (a) Cotton and (c) Jute are correct, the question is flawed. However, in many contexts, Cotton is considered the most common and representative example of a vegetable fibre used in textiles.
