It increases gradually.

Vedclass · Answer

(A) In each transition series,as we move from left to right,the nuclear charge increases by one unit at each step. Due to the poor shielding effect of $d$-electrons,the effective nuclear charge increases,which leads to an increase in the ionization enthalpy. However,this increase is not regular because of the complex interplay between increasing nuclear charge and increasing shielding effect.
