Where can you view and manage Topic Profiles that exist in the organization?

The correct choice is Topic Profiles because this is the specific section within the Marketing Cloud where users can create, view, and manage Topic Profiles relevant to their organization. Topic Profiles are essential for understanding the various themes or subjects that matter to a brand or its audience on social media. This feature allows marketers to categorize and monitor the conversations happening around those subjects to better engage with their community and respond accordingly.

The other options do not serve this purpose. For instance, Social Accounts focus on the management of the different social media accounts linked to the Marketing Cloud. Engagement Macros refer to tools used to automate and streamline engagement processes but do not pertain to viewing or managing Topic Profiles. Sentiment Models are utilized for analyzing the sentiment of posts or comments but do not provide a direct interface for managing Topic Profiles. Thus, when looking to manage Topic Profiles specifically, this is clearly the designated area within the platform.
