Answer 2

Answer:

Let's check the chemical formulae of all these ores once,

Cuprite is Cu2O, It contains, Copper and oxygen only. Chalcocite is Cu2S and it contains only copper and Sulphur, Chalcopyrite is CuFeS2, that means it contains Copper, Iron and Sulphur as well. Malchite is Cu2(CO3). That is it contains  copper, carbon and oxygen. Since only chalcopyrite contains both copper and iron, it is the correct answer among the given options.
