Final answer:

Cast iron is the ferrous metal among the provided options.


Explanation:

Ferrous metals are those that contain iron, specifically in the form of iron(II) ions (Fe^2+). In the given options, cast iron (iron(II) compounds) would be considered ferrous, making it the metal among the choices that is ferrous. Brass, aluminum, and copper are not ferrous metals since they do not primarily consist of iron(II) ions.
