Answer: Preclear their participation in IPOs, even in the absence of a conflict of interest between their participation and client interests.

**Explanation:** - **Option A** is incorrect because Standard VI(B), Priority of Transactions, recommends establishing blackout or restricted periods to prevent investment personnel from engaging in personal trading that could front-run client trades. The focus is on restricting the manager's trades, not discouraging client trading. - **Option B** is incorrect because Standard VI(B) does not require members to supply clients with copies of their personal securities transactions. Instead, it mandates that investment personnel provide their firms with duplicate copies or confirmations of all personal securities transactions. - **Option C** is correct because the recommended procedures for compliance with Standard VI(B) state that members should preclear their participation in IPOs, even when no conflict of interest exists between their participation and the client's interests. This practice aligns with ethical and professional standards aimed at preventing violations of the Code of Ethics and Standards of Professional Conduct.
