The task is to identify the correct starting material that, when treated with sodium borohydride (NaBH4) and borane (BH3), produces the specified stereoisomers of 3-methylcyclohexanone. The goal is to analyze the candidates based on their structure and reactivity to determine which one can lead to the desired products through the given reactions."}
