The correct answer is C. Publish product tutorials and guides as Knowledge articles.

This action is required because Agentforce (and other Salesforce generative AI tools) primarily use the Knowledge object as the authoritative source for Retrieval-Augmented Generation (RAG).

Knowledge Articles (C):
By publishing tutorials and guides as Knowledge articles, the content is made available for indexing in the Agentforce Data Library. The Agent's reasoning engine can then perform a semantic search over this indexed content to ground its answers, ensuring the responses provided to support agents are accurate, verifiable, and consistent with the organization's approved documentation.

Prompt Template (A):
Creating a prompt template defines the format and instructions for the AI's question/answer process, but it does not supply the necessary product content. The prompt must still be grounded in a data source, which in this case should be Knowledge.

Custom Field (B):
Adding data to a custom field is a poor and limited method for storing large, structured text like tutorials. It would not be indexed or utilized by the sophisticated RAG architecture the way the official Knowledge object is....

C is the correct answer

This action is required because Agentforce (an AI-powered agent assistant, likely within a platform like Salesforce, given the context) primarily uses Knowledge articles as its source of truth for answering agent questions.

Knowledge articles are the structured, searchable content format for support information (like tutorials and guides) that AI tools like Agentforce are designed to reference and summarize.

A. Create a prompt template for product tutorials and guides is incorrect because a prompt template defines the format of the question/request, not the source content the AI uses for answers.

B. Add an Answer Questions custom field in the product object for tutorial instructions is incorrect. While it stores data, this field wouldn't be the standard, searchable content repository that Agentforce is configured to query for comprehensive, structured answers.

A is the correct answer
