Explanation
Among the given options, zinc is the metal whose primary ore is sphalerite (zinc sulphide, ZnS), which is also an important source of cadmium as a by-product. Lead comes mainly from galena (PbS), tin from cassiterite (SnO₂), and iron from hematite/magnetite (oxides). Hence zinc is the metal chiefly associated with sphalerite.
