Select the systematic diagram that represents the correct change in the $\% \mathrm{s}-$character in the hybrid orbital of beryllium.

Arrange the following in increasing order of bond angle.

(i) $\mathrm{H}-\mathrm{C}-\mathrm{H}$ angle in ${\mathrm{CH}}_4$

(ii)  $\mathrm{Cl}-\mathrm{B}-\mathrm{Cl}$ angle in ${\mathrm{BCl}}_3$

(iii)  Adjacent $\mathrm{F}-\mathrm{S}-\mathrm{F}$ angle in ${\mathrm{SF}}_6$

(iv) $\mathrm{I}-\mathrm{I}-\mathrm{I}$ angle in ${\mathrm{I}}_3^{-}$
