Solution

The correct option is D Both Assertion and Reason are incorrect
Since $C u^{+ 2}$ shows that copper has lost $2$ electrons and has an extra $+ 2$ charge.
Therefore, $C u^{+ 2}$ ions needs to be reduced i.e. gain of electrons. On the other hand, oxidation is loss of electrons.
Therefore, $C u^{+ 2}$ ions needs to be reduced to form $C u$ metal.
