Alert - correct answer should be option 1: jute, sugarcane, linseed and rice.

Fibre crops are plants that are cultivated specifically for their fiber content. They are grown for various purposes such as making fabrics, ropes, papers, etc. Option 1 includes jute, sugarcane, linseed, and rice as fibre crops.

Jute is a long, soft, and shiny vegetable fiber used to make burlap, sacks, and other coarse fabrics. Sugarcane fibers are used in the production of bagasse, which can be used for making paper and fiberboard. Linseed (also known as flax) has fibrous stalks that are used to make linen fabric. Rice straw is used to make various products like rope, mats, and hats.

Option 2 includes cotton, maize, tobacco, and banana, but these crops are not primarily grown for fiber production. Option 3 includes cotton, hemp, jute, and mesta, and option 4 includes hemp, cotton, maize, and saffron, but they do not represent commonly recognized fibre crops.
