Which of the following is not a user role in Adobe Target?

The user role that is not part of Adobe Target is the Manager role. In Adobe Target, user roles help define the level of access and permissions that an individual has within the system. The Admin role typically has full access to all features and settings, allowing them to manage users and configurations. The Editor role is responsible for creating, modifying, and managing activities and experiences within Adobe Target. The Observer role allows users to view activities and reports without the ability to make changes.

Since "Manager" is not an officially designated role recognized within Adobe Target, it is the correct answer to the question. Understanding these distinct roles helps users navigate their responsibilities and collaborations effectively within the platform.
