In the following reaction sequence in aqueous solution, th species X, Y and Z respectively, are
`S_(2)O_(3)^(2-) overset(Ag^+)(rarr) underset("Solution")underset("Clear")(X) overset(Ag^+)(rarr)underset("Precipitate")underset("White")(Y)overset("With time")(rarr)underset("Precipitate")underset("Black")(Z)`

A

`[Ag(S_(2)O_(3))_(2)]^(3-), Ag_(2)S_(2)O_(3), Ag_(2)S`

B

`[Ag(S_(2)O_(3))_(3)]^(5-), Ag_(2)SO_(3), Ag_(2)S`

C

`[Ag(SO_(3))_(2)]^(3-), Ag_(2)S_(2)O_(2), Ag`

D
