Solution

The correct option is A violet
When chlorine is added, it will displace bromine from bromide and iodine from iodide.
Also, bromine will displace iodine from iodide. The iodine will be present in the organic layer which will appear violet.
$C l_{2} + 2 B r^{-} \to 2 C l^{-} + B r_{2}$
$C l_{2} + 2 I^{-} \to 2 C l^{-} + I_{2}$
$B r_{2} + 2 I^{-} \to B r l^{-} + I_{2}$
