______ es una solución de Amazon Ads que permite a los anunciantes comprar anuncios programáticamente para llegar a audiencias nuevas y actuales donde pasan el tiempo.

Amazon DSP (Demand-Side Platform) is the correct answer because it is Amazon's programmatic advertising solution. It allows advertisers to buy display, video, and audio ads across Amazon's owned and operated sites and apps, as well as third-party publishers and exchanges, to reach relevant audiences both on and off Amazon. The Audience Planning Tool is used for audience research and segmentation, not for programmatic ad buying. Campaign Manager is a tool for managing and optimizing Amazon Ads campaigns, but it's not the platform for programmatic media buying itself.
