Solution

The correct option is D $M g^{2 +}$
More is the reduction potential of an oxidizing agent (i.e., less ve value) it has more tendncy to undergo reduction and hence acts as a strong oxidizing agent. $∴$ Reduction potential are as follows :
$L i^{\oplus} | L i (- 3.05) < B a^{2 +} | B a (- 2.73) < M g^{2 +} | M g$
Hence, $M g^{2 +}$ acts as the strongest oxidizing agents.
