Solution

Following are the examples of redox reaction
(a) $+ 2 C u O + {0 H}_{2} \to 0 C u + {+ 1 H}_{2} O$
(b) ${+ 3 F e}_{2} O_{3} + 3 + 2 C O \to 2 0 F e + 3 + 4 C O_{2}$
(c) $2 0 K + {0 F}_{2} \to 2 + 1 - 1 K F$

(d). ${+ 2 - 1 B a C l}_{2} + {+ 1 + 6 - 2 H_{2} S O}_{4} \to {+ 2 + 6 - 2 B a S O}_{4} + 2 + 1 - 1 H C l$
Option (d) has same charges (no changes in charges), therefore, it is not an example of a redox reaction
