1. The question asks for the correct decreasing sequence of minerals produced in India in terms of their value for the year 2002-03.
2. The broad categories are Fuel minerals (like coal, lignite, petroleum, natural gas), Metallic minerals (like iron ore, bauxite, copper, zinc, manganese), and Non-metallic minerals (like limestone, dolomite, gypsum, mica).
3. Historically and particularly around 2002-03, Fuel minerals contributed the largest share to the total value of mineral production in India, mainly due to the high value of petroleum, natural gas, and coal.
4. Metallic minerals generally ranked second in value.
5. Non-metallic minerals typically ranked third in value.
6. Therefore, the correct decreasing sequence by value is Fuel minerals → Metallic minerals → Non-metallic minerals.
