In which molecule are all atoms coplanar?

Among the given species,identify the isostructural pairs.

The shape of $IF_7$ molecule is

Which of the following species are isostructural: $NO^{-}_3, CO^{2-}_3, ClO^{-}_3,$ and $SO_3$?

Statement $I$ : $SO_2$ and $H_2O$ both possess $V$-shaped structure.
Statement $II$ : The bond angle of $SO_2$ is less than that of $H_2O$.
In the light of the above statements,choose the most appropriate answer from the options given below:

Based upon $VSEPR$ theory,match the shape (geometry) of the molecules in List-$I$ with the molecules in List-$II$ and select the most appropriate option.

List-$I$ (Shape)	List-$II$ (Molecules)
$A$. $T$-shaped	$I$. $XeF_4$
$B$. Trigonal planar	$II$. $SF_4$
$C$. Square planar	$III$. $ClF_3$
$D$. See-saw	$IV$. $BF_3$
