Ferrous metals are metals containing _______________.
AI Explanation
The correct answer is D) a large percentage of iron.
Ferrous metals are those that contain a significant amount of iron. Iron is the primary constituent of ferrous metals, which include steel, cast iron, and wrought iron. These metals are known for their strength, durability, and magnetic properties, which are directly related to the presence of iron in their composition.
The other answer choices are incorrect because they do not accurately describe the definition of ferrous metals. Metals containing a large percentage of copper (option A) would be considered non-ferrous, as copper does not contain iron. Metals with no iron (option B) would also not be considered ferrous. Aluminum (option C) is a non-ferrous metal and does not contain iron in significant amounts.
