Universal Containers (UC) is using Salesforce Performance Edition.

The correct selection is B. A Partial Copy sandbox with a sandbox template provides repeatable production-sample data for training and can be refreshed on a cadence compatible with weekly sessions. Developer Pro sandboxes do not automatically carry the representative production records required for this use case. From a planning perspective, the architect must reduce uncertainty before execution by defining ownership, governance, environment purpose, prioritization, and measurable acceptance criteria. Decisions should be repeatable and visible across teams so delivery capacity, risk, and stakeholder expectations remain aligned throughout the lifecycle. The alternatives are weaker because they address a symptom rather than establishing the governance or environment decision required before implementation begins. For this scenario, the decisive point is therefore the platform behavior represented by the selected option (B. Refresh a Partial Copy sandbox every weekend and include an appropriate sandbox template.). Applying that rule consistently keeps the implementation aligned with Salesforce-supported lifecycle practices and makes the resulting change easier to review, validate, and operate across environments.
