The addition of $I^{-}$ in a solution containing ${Bi}^{3+}$ ions gives black precipitate

A white precipitate that dissolves on heating results from treating an aqueous solution of a material with diluted hydrochloric acid. Black precipitate is produced when hydrogen sulphide is exposed to the hot acidic solution.

Hence, option D is correct.
