What Org Wide Admin setting launches the Sentiment Model to analyze incoming posts?

The correct choice is the Sentiment Model because this setting specifically refers to the functionality within Marketing Cloud that analyzes the sentiment of incoming social media posts. When the Sentiment Model is activated, it utilizes various algorithms and data processing techniques to assess the emotions conveyed in posts—whether they are positive, negative, or neutral. This analysis helps businesses understand the public perception of their brand and take appropriate actions based on the feedback received.

The other options do not directly relate to the sentiment analysis functionality. Engagement Macros are used for automating responses and streamlining social engagement activities, Social Accounts pertains to managing connections with various social media platforms, and Users are related to managing permissions and roles within the organization’s Marketing Cloud setup. None of these specifically initiate the sentiment analysis, making the Sentiment Model the correct answer for the analysis of incoming posts.
