The number of lone pairs of electrons on the central atoms of $H_{2}O, SnCl_{2}, PCl_{3}$ and $XeF_{2}$ respectively, are

Which of the following compounds has the smallest bond angle $(X - A - X)$ in each series respectively?
$(A) \ OSF_2 \ \ \ \ \ \ \ \ \ OSCl_2 \ \ \ \ \ \ \ \ \ OSBr_2$
$(B) \ SbCl_3 \ \ \ \ \ \ \ \ \ SbBr_3 \ \ \ \ \ \ \ \ \ SbI_3$
$(C) \ PI_3 \ \ \ \ \ \ \ \ \ \ \ \ AsI_3 \ \ \ \ \ \ \ \ \ \ \ \ SbI_3$

Match List-$I$ with List-$II$ :

List-$I$ (Species)	List-$II$ (Number of lone pairs of electrons on the central atom)
$(a)$ $XeF_{2}$	$(i)$ $0$
$(b)$ $XeO_{2}F_{2}$	$(ii)$ $1$
$(c)$ $XeO_{3}F_{2}$	$(iii)$ $2$
$(d)$ $XeF_{4}$	$(iv)$ $3$
