Which of the following is a ferrous metal?

Explanation:
Ferrous metals contain iron in their composition. Cast iron is an alloy where iron is the main component, with carbon and silicon included, so it is ferrous. The other options do not contain iron as a main constituent—aluminium is a lightweight metal, copper is non-ferrous, and brass is copper alloyed with zinc, also non-ferrous. So the metal that fits the description is cast iron, because its iron content makes it ferrous.
