Which industry in Chhattisgarh has witnessed significant worker mobilization?

The correct answer is: Mining.

Mining is the extraction of valuable minerals or other geological materials from the earth, from an ore body, vein, seam, or deposit. These include metals, coal, oil, natural gas, and gemstones. Mining is a major industry in Chhattisgarh, and has been for centuries. The state is home to some of the largest coal reserves in India, and mining is a major source of employment for the local population. However, mining has also been a source of environmental and social problems, including pollution, deforestation, and displacement of local communities.

The other options are incorrect because:

• Steel is a metal alloy made from iron and carbon. It is a major industrial material, used in the construction of buildings, bridges, and other infrastructure. However, steel production is not a major industry in Chhattisgarh.
• Textile is a fabric made from natural or synthetic fibers. It is a major industry in India, but not in Chhattisgarh.
• Agriculture is the practice of cultivating plants and livestock. It is the primary source of livelihood for the majority of the population in Chhattisgarh. However, agriculture has not witnessed significant worker mobilization in the state.
