Which Indian mineral resource term is correctly associated with classification or identity “a combustible sedimentary energy resource”, and also with “major Gondwana coalfields occur in the Damodar, Son, Mahanadi and Godavari valleys”?

Correct Answer: Option A — Coal. Coal is correctly identified as a combustible sedimentary energy resource. Coal is also associated with major Gondwana coalfields occur in the Damodar, Son, Mahanadi and Godavari valleys. Another identifying fact about Coal is that Jharia, Raniganj and Bokaro are well-known coalfields. A further exam-relevant fact about Coal is that it is widely used in thermal power generation and metallurgical industries. Why the other options are incorrect: • Option B — Petroleum: Petroleum is a liquid fossil fuel accumulated in sedimentary basins. It is incorrect here because Petroleum is instead associated with important Indian producing regions include Assam, Gujarat, Mumbai Offshore and the Krishna-Godavari basin. • Option C — Natural Gas: Natural Gas is a gaseous fossil fuel composed mainly of methane. It is incorrect here because Natural Gas is instead associated with it occurs in several onshore and offshore sedimentary basins. • Option D — Iron Ore: Iron Ore is a metallic mineral resource used chiefly for making iron and steel. It is incorrect here because Iron Ore is instead associated with hematite and magnetite are its principal ore minerals. Exam Takeaway: Connect Coal with “a combustible sedimentary energy resource” and “major Gondwana coalfields occur in the Damodar, Son, Mahanadi and Godavari valleys” for revision.
