According to the $VSEPR$ theory,what is the shape of the water molecule $(H_2O)$?

Amongst the following,the linear species is:

Identify the molecule $(X)$ with the maximum number of lone pairs of electrons (obtained using Lewis dot structure) among $HNO_{3}$, $H_{2}SO_{4}$, $NF_{3}$, and $O_{3}$. Choose the correct bond angle made by the central atom of the molecule $(X)$. (in $^{\circ}$)

Amongst $SF_{4}$,$XeF_{4}$,$CF_{4}$ and $H_{2}O$,the number of species with two lone pairs of electrons on the central atom is $.....$ .

The shape of $AsF_5$ according to $VSEPR$ theory $:-$

According to $VSEPR$ theory,the most probable shape of the molecule having $4$ electron pairs in the outer shell of the central atom is
