Among the elements $Li$,$N$,$C$ and $Be$,the one with the largest atomic radius is

Identify the wrong statement in the following.

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 a higher ionic radius $(M^{3+})$ than the other one. The atomic number of the element $(X)$ is:

The set representing the correct order of ionic radius is
