The correct answer is D. Time Entry template .
In Workday Time Tracking, the Time Entry template controls the structure of the time entry experience for a group of workers. This includes what fields appear during time entry, how time is entered, and whether certain information must be provided before a worker can submit time. When a business wants to make a worktag required , that requirement is configured through the Time Entry template , because the template governs the entry rules and data capture requirements presented to the worker.
This is the correct design point because worktags such as cost center, project, grant, or other organizational tracking values are often needed at the point of entry for labor costing, reporting, or downstream payroll and financial processing. By making the worktag required in the template, Workday enforces that workers supply that value whenever they enter qualifying time.
The other options are not the primary place for this setup. A Worktag is the classification object itself, not the entry-rule configuration component. A Time entry code identifies the type of time being reported, such as regular or training time, but it does not generally control whether a worktag is universally required in the entry interface. A Time Calculation tag is used for calculation logic, not for entry field requirements.
So the correct answer is D. Time Entry template .
