Which of the following is an Amazon Ads technology advertising tool?

The correct answer is Amazon DSP, as it is a technology-driven advertising tool that enables advertisers to programmatically buy and manage ads across various platforms, including Amazon and third-party websites. Amazon DSP allows advertisers to leverage Amazon's extensive data and insights to target specific audiences, optimize campaigns in real-time, and maximize ad effectiveness. This platform provides a comprehensive solution for managing digital advertising efforts at scale, distinguishing it from options like Amazon Kindle, which is primarily an e-reader device, and Omnichannel Metrics, which is a measurement tool rather than a direct advertising technology.
