Solution

The correct option is C
Inversely proportional to effective nuclear charge

We know that, effective nuclear charge,

$Z e f f = z - e$

$e$ = Screening constant.

More the effective charge more will be the attraction of the nucleus on the valence electrons, thereby decreasing the size of the atom or ion.

Therefore, they are inversely proportional to effective nuclear charge.
