The subsequent treatment with dimethyl sulfide reduces the ozonide to form an alcohol. Finally, sodium borohydride is used to reduce any remaining carbonyl groups. The major product's stereochemistry is determined by the initial configuration of Limonene and the reaction conditions. The goal is to identify the correct stereoisomer from the given candidates."}
