(B) The reaction proceeds as follows: $1$. Hydrolysis of the anhydride group with $H_3O $ gives a dicarboxylic acid. $2$. Heating $(\Delta)$ causes decarboxylation of the two carboxylic acid groups,resulting in a diketone. $3$. Ozonolysis $(O_3/H_2O_2)$ of the remaining double bond cleaves the ring to form a product $P$ containing two carboxylic acid groups. Thus,the total number of $-COOH$ groups in the final product $P$ is $2$.
