The chemist is trying to identify the correct starting material that, when treated with two different reducing agents, produces (R)-3-methylcyclohexanone and (S)-3-methylcyclohexanone. The task involves analyzing the candidates to find the one that matches the required transformations and stereochemistry of the products."}
