RBAC stands for Role-Based Access Control, which is a widely adopted access control model used in information security. In this model, permissions are assigned to specific roles rather than to individual users. Users are then assigned to these roles based on their job responsibilities, allowing them to access resources and data necessary for their functions while maintaining a separation of duties and minimizing the risk of unauthorized access. This model streamlines the management of permissions, makes it easier to enforce security policies, and can be scaled easily as an organization grows.

The other choices do not accurately represent the concept of RBAC within access control. While some terms might seem relevant, they do not align with the established definitions and functionalities associated with Role-Based Access Control. This clarity reinforces the importance of understanding the terminology and application of access control models in securing information systems.
