The correct answer is: b) Assam Mineral Development Corporation (AMDC).
AMDC is a state government undertaking established in 1973 to promote the development of mineral resources in Assam. It is responsible for exploration, mining, processing, and marketing of minerals in the state. AMDC has played a key role in the development of the mineral-based industries in Assam. It has set up several mines and processing plants, and has also promoted the development of mineral-based industries by providing financial assistance and other support to entrepreneurs.
The other options are incorrect because:
- Assam Industrial Development Corporation (AIDC) is a state government undertaking established in 1972 to promote the development of industries in Assam. It is not specifically responsible for the development of mineral-based industries.
- Indian Bureau of Mines (IBM) is a central government organization under the Ministry of Mines. It is responsible for the exploration, survey, and development of mineral resources in India. It does not have a specific role in promoting mineral-based industries in Assam.
- Ministry of Mines is a central government ministry responsible for the development and regulation of the mining sector in India. It does not have a specific role in promoting mineral-based industries in Assam.
