Universal Containers wants to test agents while preserving real data and isolating from production.

The AgentForce Testing Center Implementation Guide specifies that organizations should perform all structured and regression testing in a sandbox environment replicated from production. The guide explains:

“Testing Center supports running tests safely in sandbox environments that mirror production data. This ensures realistic test conditions without impacting live systems or data.”

Option A (developer orgs) provides limited and unrepresentative data.

Option B (production org) is not recommended due to potential data integrity and security risks.

Hence, Option C is the correct and Salesforce-approved environment for safe, realistic testing of agents.
