p-amino-N, N-dimethyl laniline is added ...

p-amino-N, N-dimethyl laniline is added to a strongly acidci solution of x. The resulting solution is treated with a few drops of aqueous solution of Y to yield blue colouration due to the formation of methylene, blue. Treatment of the aqueous solution of Y with the reagent potassium hexaxyanoferrate (II) leads to the formation of an intense blue precipitate. The precipitate of the solution of Y with the solution of potassium hexacyanoferrate (III) leads to a brown colouration due to the formation of Z.
The compound X, is

A

`NaNO_(3)`

B

`NaCl`

C

`Na_(2)SO_(4)`

D

`Na_(2)S`
