(C) Ozonolysis of a benzene ring with fixed double bonds involves the cleavage of the $C=C$ bonds to form carbonyl compounds. For $1,2$-dimethylbenzene ($o$-xylene),the two resonance structures have different positions of the double bonds relative to the methyl groups. In the first structure,the double bonds are between $C_1-C_2$,$C_3-C_4$,and $C_5-C_6$. Ozonolysis yields $CH_3-CO-CO-CH_3$ and $2 \ CHO-CHO$. In the second structure,the double bonds are between $C_2-C_3$,$C_4-C_5$,and $C_6-C_1$. Ozonolysis yields $2 \ CH_3-CO-CHO$ and $CHO-CHO$. Since the products are different,the pair of $o$-xylene structures gives different products upon ozonolysis.

Which among the following pairs of the structures will give different products on ozonolysis? (Consider the double bonds in the structures are rigid and not delocalized.)
