Performance Presentation is a subsection that falls under the Duties to Clients standard. Duties to Clients typically covers aspects such as loyalty, prudence, and care; fair dealing; suitability; performance presentation; and preservation of confidentiality. "Knowledge of the Law" and "Independence and Objectivity" are subsections of the Professionalism standard (Standard I in the CFA Institute Standards of Professional Conduct), not Duties to Clients. Therefore, the correct choice is Performance Presentation (B).
