2Cu₂O(s) + Cu₂S(s) → 6Cu(s) + SO₂(g)  

This is an example of a redox reaction. Identify the correct option, mentioning the oxidized and reduced element in the reaction.

In the above mentioned redox reaction copper is reduced from +1 state to zero oxidation state and sulphur is oxidized from 2 state to +4 state. Moreover, Sulphur of Cu₂S helps copper both in Cu₂S itself and Cu₂O to decrease its oxidation number; thus, sulphur of Cu₂S is reductant whereas, Cu₂O helps sulphur in Cu₂S to increase its oxidation number, therefore, Cu(I) is an oxidant.
