The correct answer is Media interactions because media interactions refer to user behaviors and engagements with content on media platforms, such as Twitch, where users interact with specific types of content like video games. In this case, Zavier is looking to engage audiences who have interacted with video game content on Twitch, so the most relevant signal would be media interactions, as it captures these specific engagements. This enables Zavier to create more targeted audiences based on their interest in video game content on Twitch. Retail interactions would be more relevant for tracking e-commerce behaviors, and campaign remarketing would focus on users who have interacted with a brand's previous ads, rather than focusing on media-specific engagements like the one described.
