Hint: All ores are minerals but all ores are not minerals. Metals can occur in free and combined form depending on their nature.
Complete step by step answer:
The natural occurring form of Metals can contain many minerals. Some of these are used to extract metals which are called ores. In other words. Extraction of metals from minerals easily and profitably are called ores. Therefore, all ores contain minerals. However, not all minerals are ores. Most ores contain mixed metals, that is they occur in the combined state. They are in the form of compounds such as oxides, sulphides, carbonates, sulphates and silicates. Some metals (which do not react with air, water, carbon dioxide, and nonmetals) are free or natural in the earth's crust. Examples include gold and platinum. So, both the assertion and the reason are correct, but the reason is not the correct explanation for the assertion.
So, the correct option is B.
Note: Both statements are correct but neither of them is related to each other. Thus, the correct reason behind them is that they are fact based on the occurring forms of metals.
Example, Clay is the mineral of Aluminium whereas Bauxite and Cryolite are major ores of Aluminium.
Ores and minerals have a wide range of applications. Example,In case of iron ore, About 98% of them are used to make steel. Thus, steel is an alloy of iron. A very small amount of iron ore is used in making magnets, cosmetics, and paintings. Minerals are valuable sources one among them is Galena, an ore of Lead is used in batteries for energy storage. Mica is a mineral used as an insulator in electrical appliances.
