The hybridisation of $Xe$ in $XeO_3$ is

In $XeO_3$ and $XeF_6$ the oxidation state of $Xe$ is

Which one of the following is a correct pair with respect to the molecular formula of a xenon compound and the hybridization state of xenon in it?

Elements with outer electronic configuration $ns^2np^6$ are

$Xenon$ reacts best with

$Xe_{(g)} + 3F_{2(g)} \xrightarrow{573 \ K, 60-70 \ bar} XeF_{6(s)}$ ($1:20$ molar ratio).
$XeF_6 + H_2O \rightarrow XeOF_4 + 2HF$ $(Y)$
$XeF_6 + 3H_2O \rightarrow XeO_3 + 6HF$ $(Z)$
The correct statements regarding $Y$ and $Z$ are:
$I$. $Y$ has square pyramidal geometry
$II$. $Y$ has linear geometry
$III$. $Z$ has $3 \sigma, 3 \pi$ bonds and $1$ lone pair of electrons on the central atom
$IV$. $Z$ has tetrahedral geometry
