What property in ArcGIS Online controls the individual tasks that a member can perform in an organization?

The correct answer is based on the understanding that roles in ArcGIS Online specifically define what members can do within an organization. Each role comes with a set of privileges, allowing users to perform specific tasks based on their responsibilities. For example, roles can include administrator, creator, or viewer, each granting different levels of access to capabilities such as creating content, sharing maps, or managing settings.

While privileges dictate the specific tasks associated with a role, it is the role itself that categorizes members and assigns those privileges as a whole. Licenses refer to the type of subscription an organization has, whereas user types determine the broader category of access a member may have but do not encapsulate the specific tasks they can perform. Thus, role is the term that most accurately describes the overarching control of individual tasks in an organization.
