A compound (A) is greenish crystalline salt which gave the following results `:` `i)` Addition of `BaCl_(2)` solution to solution of (A) results in the formation of a white ppt. (B), which is insoluble in dil. HCl. `ii)` On heating (A), water vapours and two oxides of sulphur, (C ) and (D) are liberated leaving a red brown residue (E). `iii)` (E) dissolves in warm conc. HCl to give a yellow solution (F). `iv)` With `H_(2)S`, the solution (F) yields a pale yellow ppt. (G), which when filtered, leaves a greenish filtrate (H). `v)` Solution (F) on treatment with thiocyanate ions gives blood red coloured compound (I). Identify the substances from (A) to (I). Yellow ppt (G) is a `:`
