Solution

The correct option is A $H C l_{(a q)}$
Option (B) is correct.
$C u^{2 +}$ and $A g^{+}$ are both present in the same solution. To precipitate one of the ions and leave the other in solution, add $H C l_{(a q)}$ . $A g^{+}$ belongs to I group and get precipitated first by dil. $H C l_{(a q)}$ and then when the filtrate is warmed up and $H_{2} S$ gas is passed on it leads to the precipitation of $C u^{2 +}$ ions.
