问题如下：
Tony Brown, CFA, is the research director for Win Investment company. Recently he found some loopholes in his company's compliance system which affected its supervision and enforcement, and reflected this problem to the management. But he got no reply to solve this problem. Tony should most likely:
选项：
A.write an email to company's management to reflect this problem again.
B.write a letter of resignation immediately.
C.decline to accept supervisory responsibility in writing until the company's compliance system is reasonable perfected.
解释：
C is correct.
Tony should reject to bear supervisory responsibility until the management perfects the company’s compliance system according to the Standard IV(C) Responsibilities of Supervisors. Because he has already found the problem and reflected it to the management.
A不对么？
