Q. Which of the following reaction is a redox reaction?

$P_{2} O_{5} + 2 H_{2} O \to H_{4} P_{2} O_{7}$

$2 A g N O_{3} + B a C I_{2} \to 2 A g Cl + B a (N O_{3})_{2}$

$B a C l_{2} + H_{2} S O_{4} \to B a S O_{4} + 2 H Cl$

$C u + 2 A g N O_{3} \to 2 A g + C u (N O_{3})_{2}$

This is a redox reaction.
