AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
All minerals are naturally occurring compounds in the earth's crust, but only those minerals from which a metal can be profitably extracted are called ores. All ores are minerals, but all minerals are not ores.
Source: Chapter 3, Section 3.4 Occurrence of Metals

Always include the phrase "profitably extracted" and the one-way relationship: all ores are minerals, but not all minerals are ores.
