The correct answer is A because once Open Enrollment has been launched with incorrect benefit groups , the proper corrective action in Workday is to rescind the open enrollment event . Rescinding reverses the event for affected employees and removes the enrollment tasks that were incorrectly generated. This allows the administrator to correct the configuration and relaunch the event with the appropriate benefit groups.

Option B is incorrect because Open Enrollment cannot simply be “corrected” after it has been launched; the population tied to the event is already established and must be reset. Option C is not relevant because sending reminders does not fix incorrect group assignment. Option D is also incorrect because canceling and re-initiating without rescinding would leave prior events and data inconsistencies in place.

Rescinding ensures a clean reset of the enrollment process, allowing administrators to properly configure and relaunch Open Enrollment for the correct population without conflicts or duplicate events.
