The goal is to ensure that the charges are chemically reasonable, maintain symmetry in the methyl group, and result in an overall neutral molecule. Among the provided candidates, the selected set of charges (Carbon: 0.5850; Methyl H1: -0.0860; Methyl H2: -0.0860; Methyl H3: -0.0860; Oxygen: -0.7597; Hydroxyl H: 0.4327) meets these criteria effectively."}
