(D) When sodium is burnt in moist air,the final product obtained is $Na_2CO_3$.In moist air,sodium reacts with oxygen to form sodium oxide,which then reacts with moisture to form sodium hydroxide,and finally,it reacts with atmospheric carbon dioxide to form sodium carbonate.The complete reaction sequence is as follows:$4 Na + O_2 \rightarrow 2 Na_2O$$2 Na_2O + 2 H_2O \rightarrow 4 NaOH$$2 NaOH + CO_2 \rightarrow Na_2CO_3 + H_2O$Thus,the ultimate product is $Na_2CO_3$.

When sodium is burnt in moist air,the final product will be:
