Explanation

Correct Answer: A

According to Standard I(A) - Knowledge of the Law, if a member or candidate has reasonable grounds to believe that ongoing or imminent activities by a client or employer are illegal or unethical, they must disassociate from such activities. Failure to act while continuing association with those involved in unethical conduct may be interpreted as participation or assistance in the misconduct. In this case, the member's inaction violates Standard I(A).

Incorrect Answers: B and C

• Standard VI(A) - Disclosure of Conflicts requires members to disclose any matters that could impair their independence or objectivity. This standard does not apply to situations where a member suspects a colleague of unethical behavior. Therefore, the member has not violated Standard VI(A).
• Option C is incorrect because the member's violation pertains only to Standard I(A), not both standards.
