Answer 2

ANSWER

In the D block element there in sizes almost comparable that is there is no significant change in size of atoms because electrons are not added to outer shells. They are being added to inner shell which is shield outer electrons from nuclear charge. For each added electron a proton is added which keeps nuclear charge roughly constant.
