The correct answer is B because when a dependent reaches an age limit and loses eligibility for coverage, Workday treats this as a loss of coverage event . In this scenario, the child turning 25 triggers the termination of dependent eligibility, meaning their coverage must end. The Loss of Coverage tab within the Enrollment Event Rule is specifically designed to handle situations where an individual or dependent is no longer eligible for a benefit and coverage needs to be removed or ended.

Option A is incorrect because the Currently Covered tab is used to manage existing enrollments that remain valid, not those that must terminate due to eligibility changes. Option C applies to scenarios where coverage is being initiated or waived, not removed due to age limits. Option D is also incorrect because the Newly Eligible tab is used when a worker or dependent becomes eligible for new coverage, which is the opposite of this situation. Since the event results in the dependent losing eligibility and coverage, configuring it under the Loss of Coverage tab ensures proper termination processing within the enrollment event.
