Show Hint
Vegetable fibres:
- Composed of cellulose.
- Lignin content varies (cotton has no lignin, jute has lignin).
- Durability depends on fibre diameter and structure.
- Composed of cellulose.
- Lignin content varies (cotton has no lignin, jute has lignin).
- Durability depends on fibre diameter and structure.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of the properties of vegetable fibres.
Step 2: Detailed Explanation:
A. Vegetable fibres are mainly composed of cellulose: Correct. Cellulose is the primary component of plant fibres.
B. Vegetable fibres are mainly composed of proteins: Incorrect. Plant fibres are made of cellulose, not proteins.
C. Fibre durability is conditioned by the diameter of the fibre or fibrous aggregate: Correct. Thicker fibres are generally more durable.
D. The flexible wall of cotton fibre contains no lignin: Correct. Cotton fibres are primarily cellulose with no lignin (unlike jute or wood fibres).
Thus, statements A, C, and D are correct.
Step 3: Final Answer:
Thus, the correct answer is A, C, D only, which corresponds to option (B).
