Solution

The correct option is B the solution is aqueous
Option (A) is correct.
$H_{2} S$ will precipitate the sulphides of all the metals from the solution of chlorides of $C u$ , $Z n$ , and $C d$ if the solution is aqueous. $H_{2} S$ in neutral medium provides sufficient $S^{2 -}$ to precipitate $C u$ , $C d$ , $Z n$ , and $M n$ as sulphide..
