Comprehensive and Detailed In-Depth Explanation:

UC uses Agentforce for Sales to identify similar opportunities, aiding deal closure. Let’s determine a criterion used by the "Find Similar Opportunities" feature.

Option A: Matched opportunities have a status of Closed Won from the last 12 months.Agentforce for Sales analyzes historical data to find similar opportunities, prioritizing "Closed Won" deals as successful examples. Documentation specifies a 12-month lookback period for relevance, ensuring recent, applicable matches. This is a key criterion, making it the correct answer.

Option B: Matched opportunities are limited to the same account.While account context may factor in, Agentforce doesn’t restrict matches to the same account—it considers broader patterns across opportunities (e.g., industry, deal size). This is too narrow and incorrect.

Option C: Matched opportunities were created in the last 12 months.Creation date isn’t a primary criterion—status (e.g., Closed Won) and recency of closure matter more. This doesn’t align with documented behavior, making it incorrect.

Why Option A is Correct:

"Closed Won" status within 12 months is a documented criterion for Agentforce’s similarity matching, providing actionable insights for deal closure.
