A mixture of two salts is not water soluble but dissolves completely in dil \( \mathrm{HCl} \) to form a colourless solution. The mixture could be -
(A) \( \mathrm{AgNO}_{3} \) and \( \mathrm{KBr} \)
(B) \( \mathrm{BaCO}_{3} \) and \( \mathrm{ZnS} \)
(C) \( \mathrm{FeCl}_{3} \) and \( \mathrm{CaCO}_{3} \)
(D) \( \mathrm{Mn}\left(\mathrm{NO}_{3}\right)_{2} \) and \( \mathrm{MgSO}_{4} \)
