Explanation

According to CFA Institute Standards of Professional Conduct, particularly Standard IV(B) - Additional Compensation Arrangements:

• Standard IV(B) requires members to obtain written consent from their employer before accepting compensation or benefits that could reasonably be expected to create a conflict of interest with their employer.

• Chu's board position and the free music library access constitute additional compensation that could create a conflict of interest.

• While she appropriately discloses this to clients (which addresses Standard VI(A) - Disclosure of Conflicts), she must also comply with Standard IV(B) by obtaining written consent from her employer.

• She does not need to decline the access entirely (Option A) or exclude Rabbat from her investment universe (Option B) as long as proper disclosures and consent are obtained.
