A developer with Universal Containers recently created a flow in the developer sandbox.

The correct selection is A, C. Change sets include one flow version rather than every historical version. If an active version exists, that active version is selected; if none is active, the most recent inactive version is included, so flow activation state must be understood before migration. From a deployment perspective, the same release should be reproducible across environments, with dependencies, metadata/data differences, API behavior, and target-org constraints identified before production. Automation is valuable because it turns deployment knowledge into a controlled process rather than relying on memory or manual reconstruction. The rejected alternatives do not meet the deployment requirement because they introduce drift, ignore target-org compatibility, or substitute a convenience tool for a reproducible release artifact. For this scenario, the decisive point is therefore the platform behavior represented by the selected options (A. When a change set with a multiple versioned flow is uploaded, it includes only the active version of the flow.; C. When a change set with a multiple versioned flow is uploaded, and no active version is available, it includes the most recent inactive version of the flow.). 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.
