Option D involves ozonolysis of the alkene followed by reduction with sodium borohydride in the presence of acidic hydrogen peroxide. This process results in the formation of at least one carbonyl compound as the major product, specifically aldehydes or ketones depending on the structure of the starting alkene. The subsequent treatment with Lindlar's catalyst (Pd on CaCO3, quinoline) will convert any remaining alkyne products to cis-alkenes, providing a route to generate carbonyl compounds from both terminal and internal alkenes.
