参考答案：C
解析：
The physical and information barrier erected between departments to prevent communication of material nonpublic information from one department to another is called a "Fire Wall." Departments should be separated. For example, the investment banking and corporate finance departments of a brokerage firm should be segregated from the sales and research departments. Family member accounts who are also clients should be treated like any other client accounts and should not be given special treatment or disadvantaged.
