Answer and explanation

Correct answer: Copper

Zinc is more reactive than copper, so it displaces copper from copper sulphate solution. Copper is deposited on the zinc surface. The reaction is \(\mathrm{Zn + CuSO_4 \rightarrow ZnSO_4 + Cu}\). Zinc does not form the coating; it enters the solution as zinc sulphate.
