Fireworks Which Give Off Bright Flashes of White Light Often

Fireworks which give off bright flashes of white light often contain magnesium metal. When the magnesium burns in the presence of oxygen, it forms solid magnesium oxide, and emits a bright white light. Which of the following is the complete, balanced equation for this reaction?

A) Mg(s) + O(g) → MgO(s)
B) 4Mg(s) + O₂(g) → 2Mg₂O(s)
C) 2Mg(s) + O₂(g) → 2MgO(s)
D) Mg(s) + O₂(g) → MgO₂(s)
E) Mg(s) + O₂(g) → MgO(s)
