Verified step by step guidance

Identify the target alcohol structure from the image. The alcohol has a hydroxyl group (-OH) attached to a carbon chain.

Recognize that the reaction involves hydrogenation, as indicated by the presence of H2 and a palladium (Pd) catalyst. This typically reduces carbonyl groups to alcohols.

Examine the provided reactant structures. Look for a carbonyl group (C=O) that, when reduced, would result in the target alcohol structure.

Compare the position of the carbonyl group in each reactant with the position of the hydroxyl group in the target alcohol. The correct reactant will have the carbonyl group at the same carbon where the hydroxyl group is located in the alcohol.

Select the reactant that matches the target alcohol structure upon reduction. This reactant will have the carbonyl group in the correct position to form the desired alcohol when hydrogenated.
