RBAC is a way to control access to resources by assigning people to roles and giving each role a defined set of permissions. Access decisions come from the role a user has, so individuals gain the necessary rights through their role rather than being granted permissions one by one. This makes security and administration easier: when someone’s job changes, you update their role rather than reconfiguring many permissions.

The description that fits best is that RBAC is a method of regulating access to computer or network resources. The other statements focus on tools, day-to-day task performance, or administrative capabilities rather than the access-control model itself.
