Solution

The correct option is D $N a$
Duralumin is an alloy of aluminium that has copper and contains small amounts of magnesium, manganese, iron, and silicon: its applications requiring lightness and strength, as in aeroplane construction.So sodium is not present in Duralumin.
Hence option $D$ is correct.
