The correct answer is: c) Tribal and rural areas.
The mining sector is an important source of employment in Gujarat, especially in tribal and rural areas. The state has a large number of mineral deposits, including coal, bauxite, iron ore, limestone, and manganese. These minerals are used in a variety of industries, including steel, cement, and power generation. The mining sector employs a large number of people, both directly and indirectly. Direct employment includes jobs in mining companies, while indirect employment includes jobs in support industries, such as transportation and logistics. The mining sector is a major contributor to the state’s economy. It generates revenue through taxes and royalties, and it also provides employment opportunities for people in rural areas.
