Solution

The correct option is D
Exothermic and oxidation reaction

$2 M g + O_{2} \to M g O + h e a t + l i g h t$ . This is an oxidation reaction because Mg is oxidized and energy is liberated so it is also an exothermic reaction.It is a combination reaction because two reacts combined to give a single product.
