Which of the following change the colour of the aqueous solution of $FeCl_3$?

Which of the following orders is not correct?

$A$ mixture $X$ containing $0.02 \ mol$ of $[Co(NH_3)_5SO_4]Br$ and $0.02 \ mol$ of $[Co(NH_3)_5Br]SO_4$ was prepared in $2 \ L$ of solution.
$1 \ L$ of mixture $X +$ excess $AgNO_3 \to Y$.
$1 \ L$ of mixture $X +$ excess $BaCl_2 \to Z$.
The number of moles of $Y$ and $Z$ are:

Match the following Column-$I$ (Reaction) with Column-$II$ (colour of the product or nature):

Column-$I$ (Reaction)	Column-$II$ (colour of the product or nature)
$(A)$ $FeCl_3(aq) + NH_3(aq) \rightarrow$	$(I)$ Green ppt
$(B)$ $AgCl(aq) + NH_3(aq) \rightarrow$	$(II)$ Deep blue
	$(III)$ Brown ppt
	$(IV)$ Colourless solution

The correct answer for the sequence $(A, B)$ is:

$CuSO_{4(aq)}$ $\xrightarrow{H_2S \uparrow} M \downarrow$ $\xrightarrow[\text{Excess}]{KCN} N + O$
Then final products $N$ and $O$ are respectively.

$A$ mixture $X$ containing $0.02 \, mol$ of $[Co(NH_3)_5SO_4]Br$ and $0.02 \, mol$ of $[Co(NH_3)_5Br]SO_4$ is dissolved in water to make a $2 \, L$ solution.
$1 \, L \, of \, X + \text{Excess of } AgNO_3 \rightarrow Y \, mol \, of \, ppt.$
$1 \, L \, of \, X + \text{Excess of } BaCl_2 \rightarrow Z \, mol \, of \, ppt.$
Then $Y$ and $Z$ are respectively ...............
