• A.A sandbox should be created to use as a unified testing environment instead of deploying Change Sets directly to production.

• C.The administrators are deploying their own Change Sets over each other, thus replacing entire Page Layouts and Workflows in Production
• D.The administrators are deploying their own Change Sets, thus deleting each other's fields from the objects in production.
