Match List-$I$ with List-$II$.

List-$I$	List-$II$
$(a)$ $PCl_{5}$	$(i)$ Square pyramidal
$(b)$ $SF_{6}$	$(ii)$ Trigonal planar
$(c)$ $BrF_{5}$	$(iii)$ Octahedral
$(d)$ $BF_{3}$	$(iv)$ Trigonal bipyramidal

Choose the correct answer from the options given below.

Consider the following reactions:
$2 Cu_2S + 3 O_2 \rightarrow 2 Cu_2O + 2 SO_2$
$2 Cu_2O + Cu_2S \rightarrow 6 Cu + SO_2 \uparrow$
Here,$X$ is $Cu_2S$ and $Y$ is $SO_2$. The shape of the molecule $Y$ is:

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