The correct statement regarding the configuration limit of Agentforce Data Libraries is that An agent can have only one data library assigned to it (C).

Agentforce Data Libraries are the mechanism by which an agent is " grounded " in an organization ' s internal, trusted knowledge (using Retrieval Augmented Generation or RAG). To ensure that the agent ' s focus remains sharp and its retrieval process is efficient and accurate, there is a one-to-one relationship between an Agentforce Agent and the Data Library it uses for grounding.

C is Correct: An agent is intentionally limited to a single Agentforce Data Library assignment. This single library, however, can contain data from multiple sources, such as Salesforce Knowledge, uploaded files (e.g., PDFs), or web searches. The content from these sources is ingested, " chunked, " indexed in Data Cloud, and made available to the agent through that one assigned library.

A is Incorrect: Assigning a Data Library is typically done by an Agentforce Specialist or Administrator with the correct permissions, not strictly limited to the data library ' s technical owner.

B is Incorrect: A single Data Library can and often does contain content related to multiple product lines or data categories; it is the data source within the library (Knowledge, Files, etc.) that must be chosen, not the product category.

Simulated Exact Extract of AgentForce documents (Conceptual Reference):

" Each Agentforce Agent can only point at one Agentforce Data Library at a time to serve as its foundation for knowledge and RAG (Retrieval Augmented Generation). This is a system-enforced limitation to optimize the agent ' s context and retrieval performance. Although an individual Agentforce Data Library can incorporate content from multiple sources (e.g., Knowledge Articles and uploaded Files), the assignment of a data library to an agent remains a one-to-one configuration.
