Justify that the reaction: 2Cu₂O(s) + Cu₂S(s) → 6Cu(s) + SO₂ (g) is a redox reaction. Identify the species oxidised/reduced, which acts as an oxidant and which acts as a reductant.

Options

1. ACu₂O is oxidized, Cu₂S is reduced, Cu acts as an oxidant, and SO₂ acts as a reductant.
2. BCu₂O is reduced, Cu₂S is oxidized, Cu acts as a reductant, and SO₂ acts as an oxidant.
3. CCu₂O is oxidized, Cu₂S is reduced, SO₂ acts as an oxidant, and Cu acts as a reductant.
4. DCu₂O is reduced, Cu₂S is oxidized, SO₂ acts as a reductant, and Cu acts as an oxidant.
