Which of the following is a brand shopping experience channel available for ad placement?
Explanation: The correct answer is **Brand Stores**, as this channel specifically provides a dedicated space for brands to showcase their products and tell their brand story on Amazon. Brand Stores allow advertisers to create a customized shopping experience, featuring their full range of offerings in a visually appealing layout that enhances brand visibility and engagement. This channel is designed to facilitate brand discovery and deepen customer relationships, making it a valuable platform for ad placement. In contrast, while Twitch and Amazon Prime Video are advertising platforms, they do not serve as specialized brand shopping experience channels in the same way that Brand Stores do.
