What specific user roles are permitted to add users to a system?

The Admin Only role is correct because it is specifically designed to manage user permissions and configurations within the system. Administrators typically have elevated privileges, allowing them to perform actions such as adding, modifying, or removing users. This role is essential for maintaining the security and integrity of a system since it ensures that only authorized personnel can manage user access.

In contrast, other roles like Super User, Full User, and Basic User usually possess varying degrees of access but do not have the capability to manage user accounts effectively. Super Users might have advanced functionalities, but not necessarily the capabilities associated with adding or removing users. Full Users and Basic Users generally have limited access intended for day-to-day tasks and interactions with the system rather than user management. This clear distinction in roles is crucial for maintaining an organized hierarchy of access and responsibilities within a system.
