Which Adobe tool is primarily used for deploying and managing Experience Cloud ID Service?

Adobe Launch, now known as "Tags" in Adobe Experience Platform Data Collection, is Adobe's tag management system. It is the primary and recommended tool for deploying and managing the client-side JavaScript libraries for all Experience Cloud solutions, including the Experience Cloud ID (ECID) Service. The ECID Service is configured and deployed via its dedicated extension within the Launch interface, which simplifies implementation, version control, and rule-based deployment without needing to edit website source code directly.

B. Adobe Experience Manager is a content management system (CMS) used for building and managing websites, not for deploying tracking tags.
C. Adobe Campaign is a marketing automation platform; it consumes the ECID for personalization but does not manage its deployment on websites.
D. Adobe Workfront is a project and work management tool, unrelated to the technical implementation of web tracking libraries.
