Answer: D. West Bengal
Explanation:
- Jute is a natural fiber that is primarily grown in tropical regions like India, Bangladesh, and China.
- In India, jute cultivation is mainly concentrated in the eastern states, particularly in West Bengal, Bihar, Assam, and Orissa.

West Bengal has the maximum area under jute cultivation. This is due to the following reasons :
- Favorable climatic conditions: West Bengal has a humid climate and well-distributed rainfall, which is suitable for the growth of jute plants.
- Fertile soil: The alluvial soil found in the Ganges delta region of West Bengal is highly fertile and supports the growth of jute crops.
- Historical factors: During the British colonial period, jute cultivation was promoted in the region to support the British jute industry. This has led to the establishment of a strong jute cultivation base in West Bengal.
- Infrastructure: West Bengal has a well-established infrastructure for jute processing, including numerous mills and factories. This has encouraged farmers to continue cultivating jute in the region.
- Domestic and export demand: Jute is used in various industries, such as packaging, textiles, and handicrafts. The demand for jute products, both domestically and internationally, continues to support jute cultivation in West Bengal.

The Correct Answer is B:  Limestone

Explanation:

• Limestone (B) is the correct answer as it is used in large quantities in the cement industry.
• Limestone is the primary raw material used for the production of cement . It is a sedimentary rock composed mainly of calcium carbonate (CaCO3).
• During the cement manufacturing process, limestone is crushed and mixed with clay and other materials, then heated at high temperatures to form a material called clinker. This clinker is thenground into a fine powder, which is the final cement product.
• Other materials likegypsum, coal, and clay also play a role in the cement industry, but their usage is comparatively smaller than limestone.
• Gypsum is usedas a setting retarder to prevent cement from setting too quickly, while coal is used as a fuel source to heat the kiln during the manufacturing process. Clay is another raw material mixed with limestone to achieve the desired chemical composition for clinker production.
