To what class of minerals do gold, silver, and copper belong? A. carbonates B. native elements C. halides D. sulfates and sulfides

I have never heard of the term native elements before but that must be it since carbonates contain CO₃, halides contain a halogen, and sulfates and sulfide contain either SO₄ or SO₃. Gold, silver, and copper can all become carbonates, sulfates or sulfides, and halides. However, by them selves they don't.
