Here only reaction between Lead acetate and KI is not a redox reaction while rest other are redox reactions
A. $S n C l_{2} + H g C l_{2} \overset{R e d o x}{\to} H g ↓ S n C l_{4 s}$
B. $C u S O_{4} + K C N \to K_{2} S O_{4} + C u {(CN)}_{2} ↓ \overset{S p o n t a n e o u s (R . T .)}{\to} C u (CN) ↓ + {(CN)}_{2} ↑$
C. $P b {({CH}_{3} COO)}_{2} + K I \overset{I o n e x c h a n g e r e a c t i o n}{\to} P b I_{2} ↓ + C H_{3} C O O K$
D. $A g_{2} O + S O_{2} \overset{R e d o x}{\to} A g + S O_{3} ↑$
