Solution

The correct option is C inversely proportional to effective nuclear charge
The radius of the ion depends on the effective nuclear charge, more the charge, more heavily the electrons are attracted towards the center and lesser in the size. Hence the ionic radii are inversely proportional to effective nuclear charge, i.e., option D.
