Classification of Elements and Periodicity in Properties: JEE Main 2025 Chemistry question

Given below are the pairs of group 13 elements showing their relation in terms of atomic radius. (B < Al), (Al < Ga), (Ga < In) and (In < Tl). Identify the elements present in the incorrect pair and in that pair find out the element (X) that has higher ionic radius ($\mathrm{M^{3+}}$) than the other one. The atomic number of the element (X) is
