In the following sequence of reaction, identify the compounds (A), (B), (C ) and (D):
`underset("Solution")Na_(2)CO_(3)overset(SO_(2))rarr (A) overset(Na_(2)CO_(3))rarr (B) overset(S)underset("Heat")rarr (C ) overset(AgNO_(3))rarr (D)`
A. `Na_(2)SO_(3),NaHSO_(3),Na_(2)S,Ag_(2)S`
B. `NaHSO_(3),Na_(2)SO_(3),Na_(2)SO_(3),Na_(2)S_(3)O_(3),Ag_(2)S`
C. `NaHSO_(3),Na_(2)SO_(4),Na_(2)S,Ag_(2)O`
D. `NaHSO_(3),Na_(2)SO_(4),Na_(2)S_(2)O_(3),Ag`
