Why are metal oxides generally called basic?

Answer and explanation

Correct answer: They form salt and water with acids

The governing concept is the basic nature of many metal oxides and their neutralisation reaction with acids. For example, copper(II) oxide reacts with hydrochloric acid to form copper(II) chloride and water. This acid-neutralising behaviour supports option A. Option B describes an acidic response and is not generally true; C is false because many metal oxides are solids, and D has no chemical basis.
