Which Indian mineral resource term is correctly associated with important geographical fact “copper is used in electrical equipment, alloys and construction”, and also with “a metallic resource valued for electrical conductivity and ductility”?

Correct Answer: Option D — Copper Ore. Copper Ore is correctly identified as copper is used in electrical equipment, alloys and construction. Copper Ore is also associated with a metallic resource valued for electrical conductivity and ductility. Another identifying fact about Copper Ore is that chalcopyrite is a common copper-bearing sulphide mineral. A further exam-relevant fact about Copper Ore is that copper is used in electrical equipment, alloys and construction. Why the other options are incorrect: • Option A — Limestone: Limestone is it is also used as a flux in iron and steel processing. It is incorrect here because Limestone is instead associated with a sedimentary rock composed mainly of calcium carbonate minerals. • Option B — Uranium: Uranium is ore processing produces uranium concentrate for the nuclear-fuel cycle. It is incorrect here because Uranium is instead associated with a radioactive mineral resource used as nuclear fuel. • Option C — Coal: Coal is it is widely used in thermal power generation and metallurgical industries. It is incorrect here because Coal is instead associated with a combustible sedimentary energy resource. Exam Takeaway: Connect Copper Ore with “copper is used in electrical equipment, alloys and construction” and “a metallic resource valued for electrical conductivity and ductility” for revision.
