Final answer:
Grouping D, which includes Admin, Standard User, Sync User, and Analytics User, represents actual roles typically found within software systems, defining different levels of user permissions and access to functionalities.
Step-by-step explanation:
The grouping that only includes actual roles that users may be assigned is option D: Admin, Standard User, Sync User, and Analytics User. These roles represent common user access levels or permissions in many software systems. The roles typically define the level of access a user has to the platform’s features. For example, an Standard User may have access to use most features, but cannot alter system settings, which is a capability reserved for an Admin. Sync User could represent a user who can synchronize data between systems, and Analytics User is usually assigned to individuals who need to generate and view reports or analytics.
