Answer: B - When information has been changed and the change is reflected, it has been committed. The commit operation completes a transaction and executes all changes just made by the user. These changes can be made to data or schema information. Because these changes are committed, they are then available to all other applications and users. If a user attempts to commit a change and it cannot complete correctly, a rollback is performed. This ensures that partial changes do not take place and that data are not corrupted.
