Explanation

Correct Answer: C

Why C is correct:

According to the CFA Institute Standards of Professional Conduct, members and candidates must comply with the CFA Institute Professional Conduct Program (PCP) investigations. Standard I(E): Professionalism - Misconduct states that members must not engage in any professional conduct involving dishonesty, fraud, or deceit. More specifically, Standard VII(A): Conduct as Members and Candidates in the CFA Program requires cooperation with the CFA Institute Professional Conduct Program.

Key points:

1. CFA Institute Requirements Supersede Local Laws: When local laws require client confidentiality, members must still comply with CFA Institute requirements to disclose information during PCP investigations.
2. Duty to Cooperate: Members have an obligation to cooperate with the CFA Institute's Professional Conduct Program investigations.
3. Violation: Refusing to disclose information during a CFA Institute investigation constitutes a violation of the Standards, even if local laws require confidentiality.

Why A is incorrect: Disclosing information about illegal activities to local authorities is generally permitted under the Standards. Standard I(A): Knowledge of the Law states that members must comply with applicable laws. If local laws require reporting of illegal activities, this disclosure would not violate the Standards.

Why B is incorrect: Refusing to share details of a prospective client with the marketing department is not necessarily a violation. While firms may have internal policies about sharing information, this is not specifically addressed in the Standards as a violation when balanced against client confidentiality requirements.

Summary: The CFA Institute Standards require cooperation with PCP investigations, and this requirement takes precedence over local confidentiality laws. Therefore, refusing to disclose information during a CFA Institute investigation is a violation of the Standards.
