_______ es una herramienta que te permite generar automáticamente recursos personalizables con un fondo, logotipo, título u otro texto adaptados.

Responsive eCommerce Creatives (REC) is the correct answer because it is a tool designed to automatically generate customizable ad creatives. It allows advertisers to input elements like a background, logo, headline, or other text, and the tool then adapts these to create various ad variations efficiently. This automation helps in scaling ad creation and testing. Image generation is a broader concept that may or may not include the automatic customization aspect described. Brand Innovation Lab is a program focused on advanced advertising solutions and brand building, not a tool for automated creative generation.
