The ionic equation for the reaction between zinc and aqueous copper ions is shown.

Zn( s)+Cu2+(aq)→Zn2+(aq)+Cu( s)\mathrm{Zn}(\mathrm{~s})+\mathrm{Cu}^{2+}(\mathrm{aq}) \rightarrow \mathrm{Zn}^{2+}(\mathrm{aq})+\mathrm{Cu}(\mathrm{~s})

Which statement about this reaction is correct?

A

Copper ions are oxidised and their oxidation state changes.

B

Copper ions are reduced because they lose electrons.

C

Zinc atoms are oxidised and their oxidation state changes.

D

Zinc atoms are reduced because they gain electrons.
