The correct answer is B because the Benefit Events Status report is specifically designed to track and monitor benefit events across various stages, including in progress, submitted, completed, or cancelled . This report provides visibility into event activity at the individual worker level and is commonly used by benefits administrators to monitor ongoing events such as new hire benefit enrollments . It allows administrators to identify which employees still need to complete their elections and ensures timely follow-up.

Option A is incorrect because the Benefit Group Audit report focuses on validating worker assignment to benefit groups and identifying eligibility overlaps, not event progress. Option C is also incorrect because the Benefit Census report provides a snapshot of current benefit enrollments rather than tracking event status. Option D is incorrect because Open Enrollment Status is specific to open enrollment events and does not provide detailed tracking for other event types like new hire events. For monitoring active benefit events, especially new hire enrollments, the correct report is Benefit Events Status .
