What is the meaning of $VSEPR$?

Among the compounds shown below,which one reveals a linear structure?

Select the incorrect match regarding molecular geometry:
Statement $-$ Shape $-$ Example
$A$. $SF_4$ $-$ See-saw $-$ $SF_4$
$B$. $BrF_3$ $-$ $T$-shaped $-$ $BrF_3$
$C$. $XeF_4$ $-$ Square planar $-$ $XeF_4$
$D$. $ICl_2^-$ $-$ Linear $-$ $ICl_2^-$

Match the following?

Molecule	Geometry
$(a) SnCl_2$	$(i)$ Angular (or) Bent
$(b) XeF_4$	$(ii)$ See-saw
$(c) ClF_3$	$(iii)$ Square pyramidal
$(d) IF_5$	$(iv)$ $T$-shape
-	$(v)$ Square planar

Give the correct order of initials $T$ or $F$ for following statements. Use $T$ if statement is true and $F$ if it is false:
$(I)$ The order of repulsion between different pair of electrons is $lp-lp > lp-bp > bp-bp$.
$(II)$ In general,as the number of lone pair of electrons on the central atom increases,the deviation of the bond angle from the normal bond angle increases.
$(III)$ The number of lone pairs on $O$ in $H_2O$ is $2$,while on $N$ in $NH_3$ is $1$.
$(IV)$ The structures of xenon fluorides and xenon oxyfluorides could not be explained on the basis of $VSEPR$ theory.

Consider the species $CH_4$,$NH_4^+$ and $BH_4^-$. Choose the correct option with respect to these species.
