The correct order of atomic radii of the elements $O$,$N$,$S$ and $P$ is

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:

On going down a main sub-group in the periodic table (example $Li$ to $Cs$ in $IA$ or $Be$ to $Ra$ in $IIA$),the expected trend of changes in atomic radius is a

The ionic radii of $F^{-}$ and $O^{2-}$ respectively are $1.33 \ \mathring{A}$ and $1.40 \ \mathring{A}$,while the covalent radius of $N$ is $0.74 \ \mathring{A}$. The correct statement for the ionic radius of $N^{3-}$ from the following is:

The radii of $F$,$F^{-}$,$O$ and $O^{2-}$ are in the order of:

Which of the following orders is correct?
