B. Resonance occurs as a result of sympathetic vibrations. Even though Fluorine is expected to have the highest electron affinity as it has the highest electron negativity, it is not. Why does argon have a larger atomic radius? As you move across an element period (row), the overall size of atoms decreases slightly. This is because the number of protons increases (sodium has 11, argon has 18) so the nuclear charge increases. Argon is bigger than chlorine because argon being inert its outermost shell is completely filled thus a force of repulsion acts between the outermost electron and the nucleus causing it to grow bigger in size than chlorine.
