(B) To determine if species are isostructural,we check their hybridization and geometry:$1$. $PF_6^-$ ($sp^3d^2$,octahedral) and $SF_6$ ($sp^3d^2$,octahedral) are isostructural.$2$. $SiF_4$ ($sp^3$,tetrahedral) and $SF_4$ ($sp^3d$,see-saw) are $NOT$ isostructural.$3$. $IO_3^-$ ($sp^3$,pyramidal) and $XeO_3$ ($sp^3$,pyramidal) are isostructural.$4$. $BH_4^-$ ($sp^3$,tetrahedral) and $NH_4^+$ ($sp^3$,tetrahedral) are isostructural.Thus,the pair $SiF_4$ and $SF_4$ is not isostructural.

List-$I$	List-$II$
