    B)  \[{{(N{{H}_{4}})}_{2}}S{{O}_{4}}.FeS{{O}_{4}}.6{{H}_{2}}O\]

    C)  \[F{{e}_{3}}{{[Fe{{(CN)}_{6}}]}_{2}}\]

    D)  \[{{[Fe{{(CN)}_{6}}]}^{3-}}\]

    Correct Answer: A

    Solution :

                    \[F{{e}_{4}}{{[Fe{{(CN)}_{6}}]}_{3}}\xrightarrow[{}]{}4F{{e}^{3+}}+3{{[Fe{{(CN)}_{6}}]}^{4-}}\]
