According to Oracle documentation2, the delivered role that can access the full functionality of Functional Setup Manager is Application Implementation Manager. Functional Setup Manager is a tool that enables you to manage and perform all of the setup tasks required for an application implementation. Application Implementation Manager is a predefined role that grants access to Functional Setup Manager and all of its features, such as setup tasks, implementation projects, setup export and import, and setup reports. Therefore, option A is correct. Option B is incorrect because Functional Setup Manager Superuser is not a delivered role.
Option C is incorrect because IT Security Manager is a role that grants access to security-related tasks, not Functional Setup Manager. Option D is incorrect because any functional user does not have access to Functional Setup Manager by default. Option E is incorrect because Application Implementation Consultant is not a delivered role.
