Which of the following ions has the largest ionic radius?

$A, B, C, D$ and $E$ are elements with atomic numbers $13, 11, 9, 7$ and $16$ respectively. Among these elements,the ion of an element $X$ has the largest size and the ion of an element $Y$ has the smallest size. $X$ and $Y$ are respectively (Assume that all ions have the nearest inert gas configuration).

Which of the following ions is the smallest in size?

In $K^{+} F^{-}$ ionic,the ionic radius of $F^{-}$ is more,while the atomic radius of $K^{+}$ is:

Which of the following ions will have the largest ionic radius?

Which of the following represents the correct order of ionic radii?
