Question

Quizplus · Accepted Answer

The correct answer is sulfides. This is because the sulfide mineral class contains the anion S⁻². The other options, oxides, halides, and sulfates, do not contain this anion. Oxides contain oxygen anions (O²⁻), halides contain halogen anions (Cl⁻, F⁻, Br⁻, I⁻), and sulfates contain the sulfate anion (SO₄²⁻).
