Which of the following is a metallic mineral resource?

Explanation:
Metallic mineral resources are ores that supply usable metals. Among the options, bauxite is the primary ore of aluminum, containing aluminum oxides from which the metal is extracted. Gypsum is a non-metallic mineral used in plaster and cement; halite is rock salt; sand is mostly silica. None of those yield metals in an ore form, so they’re non-metallic minerals. Bauxite stands out because it is a source of a metal, making it the correct choice.
