Trisilyamine $(SiH_3)_3N$ is

Which of the following represents pairs of isostructural species?

Identify the pair in which the geometry of the species is $T$-shape and square pyramidal,respectively.

Given below are two statements:
Statement $I$: The number of compounds among $SO_2$, $SO_3$, $SF_4$, $SF_6$ and $H_2S$ in which sulphur does not obey the Octet rule is $3$.
Statement $II$: Among $[H_2O, ClF_3, SF_4]$, $[NH_3, BrF_5, SF_4]$, $[BrF_5, ClF_3, XeF_4]$ and $[XeF_4, ClF_3, H_2O]$, the number of sets in which all the molecules have one lone pair of electrons on the central atom is $1$.
