In Workday, compensation packages are used to group compensation plans that are presented and assigned during staffing events , such as Hire or Change Job. These packages are designed to include plans that are transactionally assigned and visible during compensation proposals.

A one-time payment plan is explicitly supported within compensation packages and is commonly used for sign-on bonuses, relocation payments, or other ad hoc payments offered during hiring.

Calculated plans and retirement plans are not assigned directly through compensation packages. Calculated plans are system-derived and depend on other plans, while retirement plans are managed through Benefits configuration. Future payment plans are handled separately and are not eligible for inclusion in compensation packages.

Therefore, the only valid option is One-time payment plan , making option D correct.
