请问答案C enforcing investment related policies 错在哪里？

问题如下：

In her meeting with Rayne supervisors, Mutini is least likely correct with regard to:

选项：

A.communicating with staff. B.undertaking periodic reviews. C.enforcing investment-related policies.

解释：

根据CFA Institute的《道德规范与专业行为准则》，标准IV(B)额外收入安排，要求员工在接受额外报酬时需确保不会与客户的利益或公司政策发生冲突。OAM的年度竞赛奖金并不违反这一标准，因为它与销售业绩直接挂钩，且没有涉及客户利益或额外的报酬安排问题。
