Solution

The correct options are
A
$M g (s) \to M g^{2 +} + 2 e^{-}$

C
$Z n (s) \to Z n^{2 +} + 2 e^{-}$

The reaction in which loss of electron takes place is called oxidation reaction. The reaction in which the gain of electron takes place is called a reduction reaction. The reaction in which oxidation and reduction both take place simultaneously is called redox reaction. The reactions which are showing an oxidation reaction are:

$M g (s) \to M g^{2 +} + 2 e^{-}$

$Z n (s) \to Z n^{2 +} + 2 e^{-}$
