Enabling a report as a worklet and assigning it to a dashboard does not automatically make it visible. The Recruiting dashboard (or any dashboard in Workday) must be configured to include the worklet explicitly. This is a common oversight---report designers assume that enabling a report as a worklet is sufficient, but the dashboard itself must be updated in configuration to display that worklet tile.

From the Workday reporting materials: ''Dashboards provide an interface to view multiple worklets. Even if a report is enabled as a worklet, the dashboard configuration determines which worklets are visible to end users.''

Other options are less relevant: exceeding 100 rows only impacts loading performance, not visibility; security issues would typically block data, not hide the worklet entirely; and required setup applies to whether the worklet is optional or required, but it must still be added to the dashboard.

Thus, the correct reason is B. You need to configure the Recruiting dashboard to include the worklet.
