Answer:
a. Power user
Step-by-step explanation:
In this situation, the administrator should create a power user account for the user. This is a user who uses advanced features of computer hardware, operating systems, programs, or websites that are not used by the average user as well as having similar permissions to an administrator without the ability to edit or view subscriptions or other users and they do not have access to billing information. Thus in this scenario, a power user account will allow the individual to complete all of their required tasks but at the same time preventing them from accessing administrator level rights.
