RAS question
Which crop is called 'Golden Fiber'?
Correct answer: (D) Jute.
Jute is called the golden fibre.
Explanation
Jute is called the golden fibre, which is why option D is correct. At an ICAR-NINFET natural fibre event, Dr. G. Kar described jute as the golden fibre while highlighting its role in reducing carbon footprints and strengthening the national economy. For this RAS question, the important classification point is the crop-name association, not a Rajasthan production statistic. Mesta, used as a jute substitute, is grown only in limited areas of Banswara and Kota. So the exam answer remains jute, with mesta remembered only as the local substitute note.
Why the other options are wrong
- (A) Silk is a different fibre and is not called the golden fibre.
- (B) Cotton is associated here with white gold, so it does not match the golden-fibre label asked in the question.
- (C) Hemp is not identified as the golden fibre by Indian Council of Agricultural Research.
Concept
This tests standard agricultural-crop terminology within economic geography. It recurs in RAS because crop nicknames and Rajasthan-specific substitutes are quick ways to check factual clarity in agriculture questions.
