In the activity series, $Zn$ is relatively easy to oxidize
to $Zn^{2 +}$ , while $Cu$ is relatively inactive. Therefore, if $Zn$ metal were placed in a solution containing $Cu^{2 +}$ ions, $Zn$ would be oxidized to $Zn^{2 +}$ ions and $Cu^{2 +}$ would be reduced to $Cu$ metal. Both statements are true, and statement II gives the reason that statement I is correct. The correct answer is therefore true, true, correct explanation.
