Solution

The correct option is A oxidation
Oxidation is the loss of electrons or an increase in oxidation state by a molecule, atom, or ion. A reduction is the gain of electrons or a decrease in oxidation state by a molecule, atom, or ion.
$C u \to C u^{2 +} + 2 e^{-}$ is a oxidation reaction and in a cell, oxidation reaction take place at anode.
