Answer:

Out of these elements, the most stable are the noble gases as their valence shells are filled and thus are unreactive.

Thus the stable elements are Ar and Ne in this set of elements.

PS - You probably won't need this, but Mg is also stable because of a full filled subshell but don't use this.
