(D) The salt $A$ is $AgNO_3$.$1$. Reaction with $Cu$: $2AgNO_3 + Cu \rightarrow Cu(NO_3)_2 + 2Ag$. The $Cu^{2+}$ ions formed in the solution impart a blue color.$2$. Reaction with $HCl$: $AgNO_3 + HCl \rightarrow AgCl \downarrow + HNO_3$. $AgCl$ is a white precipitate.$3$. Reaction with $Conc. H_2SO_4$: $AgNO_3 + H_2SO_4 \rightarrow HNO_3 + AgHSO_4$. The $HNO_3$ decomposes to release $NO_2$ gas,which appears as brown fumes.
