Solution

The correct options are
B it combines with oxygen
D absorbs massive amount of air while burning
The increase in mass is due to the fact that oxygen from the air has combined with the magnesium to make magnesium oxide, $M g O$ . The chemical equation, $M g + O_{2} \to M g O$ shows this reaction but it needs to be balanced to make $2 M g + O_{2} \to 2 M g O$
