उत्तर
C is silver chloride which is soluble in ammonia.
Pungent smelling gas B is ammonia.
White solid A is ammonium chloride.
\[\ce{NH4Cl(s) ->[NaOH] NH3(g) + H2O + NaCl}\]
\[\ce{NH3(g) ->[Red litmus] blue litmus}\]
\[\ce{\underset{\text{A}}{NH4Cl(s)} ->[AgNO3][HNO3] \underset{\text{C}}{AgCl(s)}}\]
