Ozonolysis cleaves alkenes at the double bond, producing carbonyl compounds. To find the reactant, reverse the process: combine the carbonyl carbons from products a, b, and c to reform the original double bonds.
The products are: , , and . The correct reactant must have double bonds that, upon cleavage, yield these exact fragments. Only the structure with a central dialdehyde connected to two different alkene units satisfies this.
Final Answer: The third option is the correct reactant structure.
