OGL content can be tailored to individual users based on Fusion security roles (option C), which determine access and visibility within the application. This ensures content aligns with users' permissions and responsibilities. User preferences (option A) and organizational hierarchy (option B) may influence indirectly but aren't primary mechanisms, while manager delegation (option D) is unrelated to content display. Fusion security roles provide a precise, system-driven method for personalization, leveraging Oracle's role-based architecture effectively.
