Just prior to a new deployment the Salesforce administrator, who configured a new order fulfillment process feature in a developer sandbox, suddenly left the company.
Ag part of the UAT cycle, the users had fully tested all of the changes in the sandbox and signed off on them; making the Order fulfillment feature ready for its go-live in the production environment.
Unfortunately, although a Change Set was started, it was not completed by the former administrator.
A developer is brought in to finish the deployment.
What should the developer do to identify the configuration changes that need to be moved into production?

• A. Leverage the Setup Audit Trail to review the changes made by the departed Administrator and identify which changes should be added to the Change Set.
• B. In Salesforce setup, look at the last modified date for every object to determine which should be added to the Change Set.
• C. Set up Continuous Integration and a Git repository to automatically merge all changes from the sandbox metadata with the production metadata.
• D. Use the Metadata API and a supported development IDE to push all of the configuration from the sandbox into production to ensure no changes are lost.
