Which one of the following is the correct decreasing sequence in terms of the value (in rupees) of the minerals produced in India in the year 2002-03?

The correct sequence is Fuel minerals—non-metallic minerals—Metallic minerals. Explanation: 1. Fuel minerals (coal, crude petroleum, natural gas) consistently account for the largest share of the value of mineral production in India due to high demand for energy. 2. Non-metallic minerals (such as limestone, mica, gypsum, etc.) are produced in large quantities and have diverse industrial applications (e.g., cement, construction), contributing significantly to the overall value, often surpassing metallic minerals. 3. Metallic minerals (like iron ore, bauxite, copper, etc.), while crucial, generally have a lower aggregate value compared to fuel minerals and often non-metallic minerals in the Indian context for the specified period. Therefore, for the year 2002-03, the decreasing order of value was Fuel minerals, followed by Non-metallic minerals, and then Metallic minerals. Analyzing the options: A) Incorrect. Fuel minerals are the highest in value, not metallic minerals. B) Incorrect. Non-metallic minerals had a higher value than metallic minerals. C) Incorrect. Fuel minerals are the highest in value, not metallic minerals. D) Correct. This sequence accurately reflects the relative values of mineral production categories in India for 2002-03.
