A) 2

B) 3

C) 1

D) 4

Answer:

Option A

Explanation:

Plan  Reactant is cyclic  anhydride and changes to dicarboxylic acid on hydrolysis

Also, there is decarboxylation on heating if there is keto group w.r.t -COOH  group. Ozonolysis cleaves $(C=C) $bond and $H_{2}O_{2}$   oxidises -CHO to -COOH group
