Which Indian mineral resource term is correctly associated with important geographical fact “it is also used in batteries and certain chemical industries”, and also with “a metallic mineral important in steel and alloy manufacture”?

Correct Answer: Option D — Manganese Ore. Manganese Ore is correctly identified as it is also used in batteries and certain chemical industries. Manganese Ore is also associated with a metallic mineral important in steel and alloy manufacture. Another identifying fact about Manganese Ore is that pyrolusite is an important manganese-bearing mineral. A further exam-relevant fact about Manganese Ore is that it is also used in batteries and certain chemical industries. Why the other options are incorrect: • Option A — Bauxite: Bauxite is alumina is extracted from bauxite before electrolytic aluminium smelting. It is incorrect here because Bauxite is instead associated with the principal ore used for aluminium production. • Option B — Mica: Mica is muscovite and phlogopite are important mica varieties. It is incorrect here because Mica is instead associated with a sheet-silicate mineral group that splits into thin elastic sheets. • Option C — Copper Ore: Copper Ore is copper is used in electrical equipment, alloys and construction. It is incorrect here because Copper Ore is instead associated with a metallic resource valued for electrical conductivity and ductility. Exam Takeaway: Connect Manganese Ore with “it is also used in batteries and certain chemical industries” and “a metallic mineral important in steel and alloy manufacture” for revision.
