Answer: (D)

Verified step by step guidance

1. Identify the functional groups in the starting material. The molecule contains an aldehyde group (CHO) and a secondary alcohol (OH) on a cyclohexane ring.
2. Recognize the reagent used in the reaction. PCC (Pyridinium chlorochromate) is a mild oxidizing agent that can oxidize primary alcohols to aldehydes and secondary alcohols to ketones.
3. Determine which functional group will be affected by PCC. In this case, the secondary alcohol will be oxidized to a ketone, while the aldehyde group will remain unchanged.
4. Predict the structure of the product. The secondary alcohol on the cyclohexane ring will be converted to a ketone, resulting in a cyclohexanone structure with an aldehyde group on the side chain.
5. Draw the final product structure, ensuring that the aldehyde group remains unchanged and the secondary alcohol is now a ketone. The product will have a ketone on the cyclohexane ring and an aldehyde group on the side chain.
