    This one most probably should be sulphide. As these deposits are known to have formed by precipitation of metallic sulphides from water that is probably discharged at high temperature (usually from 250°C to 400°C) from hydrothermal vents along mid ocean ridges. Copper-rich sulfide deposits in the Troodos Ophiolite of Cyprus are a well-known example of oceanic ridge sulfide deposits . So correct option should be (A).
