Universal Containers operates a customer self-service portal supported by an Agentforce Service Agent.

The correct answer is B because a Knowledge-based Agentforce Data Library is the correct managed source for approved service and compliance content. Salesforce Knowledge already handles the article lifecycle, including publication state and article governance, while Agentforce Data Library makes that content searchable for AI grounding. Filtering to published articles prevents draft, archived, or outdated content from being used in customer-facing responses. Option A adds unnecessary Flow-based retrieval and bypasses the native semantic retrieval pattern. Option C may work for custom indexed content, but it is less efficient when the authoritative source is already Salesforce Knowledge. The clean architecture is to connect the data library to Knowledge, restrict the indexed scope, and allow the agent to retrieve semantically relevant approved articles.
