Which of the following pair of group 13 elements have similar atomic radius

Atomic radius order :Tl~In >Al > Ga > B                           OR                         B < Ga < Al < In ~ Tl"In,Tl"have almost all same atomic radii,due to poor shielding effect by innershell f-electrons and d-electrons the valency shell electrons in "Tl" are strongly attracted by nucleus and hence the sizes of "In" and " Tl " are almost all same.
