What contains the configuration changes made in an instance (i.e. changes in a form) and helps to implement the changes from the Dev environment to another environment?
Correct Answer: A
Explanation
Update sets are the configuration changes made in an instance, such as changes in a form, that can be exported from one instance and imported into another. This helps to implement the changes from the Dev environment to another environment, such as Test or Prod. Update sets capture the changes made to system properties, UI actions, business rules, workflows, and other customizations.
