The correct answer is: The Privacy Sandbox proposes to limit cross-site and cross-app user tracking on Chrome and Android

Explanation: The Privacy Sandbox initiative by Google is designed to enhance user privacy by reducing the ability to track users across different sites and apps. It introduces new technologies that allow for interest-based advertising, re-engaging audiences, and performance measurement without relying on third-party cookies. By storing data locally on users’ devices and adding noise to conversion data, it ensures that user-specific tracking is minimized, thereby protecting privacy while still supporting essential advertising use cases.
