Starting with cyclooctatetraene and maleic anhydride, the reactions yield a diene that subsequently reacts with cyclopentadiene in a Diels-Alder reaction. The task is to determine the structure of the major isomer of the final product, considering stereochemistry and the nature of the reactants. The major isomer can be identified by analyzing the stereochemical configurations provided in the candidate options."}
