The correct sequence which shows decreasing order of the ionic radii of the element is
As we learnt in
Size of isoelectronic species -
Smaller the value of z/e, larger the size of that species.Smaller z means effective nuclear charge is small hence size is large.
For isoelectronic species, as effective nuclear charge increases, ionic radii decreases. Nuclear charge is maximum of the specie with maximum protons .
Order of nuclear charge:
Thus increasing order of ionic radii
This option is correct.
