Electronegativity is a measure of an atom's ability to attract shared electrons towards itself in a chemical bond. Noble gases have the general electronic configuration of \mathrm{ns^{2}np^{6}}. Since, noble gases do not form bonds, electronegativity is not applicable to noble gases.

Hence Option 4 is correct.
