The correct selection is A, D. The org development model enables automated deployment from source and automated change tracking through source-driven workflows. It does not automatically fix defects or make sandbox provisioning a defining built-in characteristic. From an ALM perspective, the controlling principles are a clear source of truth, repeatable change tracking, controlled promotion, testable release artifacts, and traceability from requirement through production. Mature teams separate the lifecycle from any single tool so the process remains consistent even when the deployment mechanism changes. The rejected alternatives either describe a specific tool rather than a lifecycle capability or omit the source-control and traceability needed for repeatable enterprise delivery. For this scenario, the decisive point is therefore the platform behavior represented by the selected options (A. Automated deployment; D. Automated change tracking). 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.
