$B$. $FOF$ bond angle is less than $104.5^{\circ}$.
$C$. Oxidation state of $O$ is $-2$.
$D$. Molecule is bent $V$-shaped.
$E$. Molecular geometry is linear.
Which of the following options is correct?

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 $1$.
