The correct option is C. 
For an element to be unreactive and stable, it must have eight electrons in its outermost shell. Sodium has an atomic number of 11 and thus have only one electron in its outermost shell. This makes sodium very reactive and it is always very willing to react with suitable elements in order to become stable.
