Option A is correct because Account Summarization uses a cross-object graph to define which objects and relationships are included in the generated summary. Salesforce Help states that administrators can create cross-object graphs from a predefined Account Summarization template to provide a complete view of an account and its related objects. This directly matches the requirement to include Account data and related Healthcare Provider and Contact Point Address information in the summary.
The phrase "historical data" is also important. Salesforce Account Summarization setup includes configuring history tracking for the fields included in the template, so Agentforce can summarize recent changes from the selected objects and fields. The cross-object graph defines the relationship structure, while field history tracking provides the change history used in the summary.
Option B, Actionable Relationship Center, is not the best answer. Actionable Relationship Center is used to visualize related records and relationships, but the Account Summary configuration specifically relies on cross-object graphs. Option C, Affiliation Alignment Rules, is unrelated because those rules support territory alignment for affiliated accounts, not Account Summary object relationships. Therefore, the consultant should use a Cross-Object Field History Graph to define the Account, Healthcare Provider, Contact Point Address, and related-object structure used by Agentforce Account Summary.
