8.0 g of an element X react with an excess of copper (ll) tetraoxosulphate (lV) solution to deposit 21.3 g of copper. The correct equation for the reaction is?

(Cu = 64).

A. X_(s) + CuSO_4(aq) → Cu_(s) + XSO_4(aq)
B. X_(s) + 2CuSO_4(aq) → 2Cu_(s) + X(SO₄)_2(aq)
C. 2X_(s) + CuSO_4(aq) → Cu_(s) + X₂SO_4(aq)
D. 2X_(s) + 3CuSO_4(aq) → 3Cu_(s) + X₂(SO₄)_3(aq)
