If Iris has a business goal to link customers to their website so they can order pizza, which recommended ad solution would meet their needs?

The correct answer is "Sponsored Display" because this ad solution is designed to help advertisers reach potential customers both on and off Amazon, including driving traffic to external websites. Sponsored Display ads can be used to target relevant audiences based on their browsing behavior and interests, and they can link directly to an external website, such as Iris’s pizza ordering page. This makes it ideal for driving website visits and achieving Iris’s goal of linking customers to their website. In contrast, "Sponsored Products" is primarily used to promote products within Amazon's ecosystem, and "Brand Stores" creates a dedicated brand page within Amazon but does not link directly to external websites.
