Bihar is a significant producer of which cash crop?

The correct answer is: a) Jute.

Jute is a long, soft, and shiny fiber that is used to make a variety of products, including burlap, twine, and carpet. It is the second most important natural fiber in the world, after cotton.

Bihar is the largest producer of jute in India. The state accounts for about 50% of India’s jute production. Jute is grown in the Gangetic plain of Bihar, where the climate is ideal for its cultivation.

Jute is a cash crop, which means that it is grown for sale rather than for consumption. It is a major source of income for farmers in Bihar.

The other options are incorrect because:

• Rubber is not a major crop in Bihar.
• Coconut is not grown in Bihar.
• Sugarcane is grown in Bihar, but it is not as important as jute.
