Answer
A → Silver nitrate
B → Hydrochloric acid
C → Silver chloride
Explanation
Solution A is silver nitrate which reacts with acid B i.e., Hydrochloric acid to give a white precipitate C of AgCl which is insoluble in nitric acid but soluble in ammonium hydroxide.
AgNO3 + HCl ⟶ AgCl ↓ + HNO3
AgNO3 + HNO3 ⟶ no reaction
AgCl + 2NH4OH ⟶ [Ag(NH3)2Cl)] + 2H2O
