Full Detailed in Depth Explanation:

In Oracle HCM Cloud, statuses control various aspects of a worker’s record, and the ability to create additional values depends on the status type:

A (Payroll Status): This refers to payroll-specific statuses (e.g., Processed, Paid), which are system-defined and tied to payroll processes. These are fixed and cannot be extended with additional values.

B (Assignment Status): This governs the status of a worker’s assignment (e.g., Active, Suspended). Oracle allows you to create additionalUser-Defined Assignment Statusesvia the "Manage Assignment Status" task, enabling customization (e.g., "On Leave – Special Circumstance") while preserving system statuses like Active or Inactive.

C (HR Status): This is a broad term, but in context, it typically refers to the Person-level status (e.g., Active, Terminated), which is system-defined and not extensible with additional values.

The Oracle documentation highlights that Assignment Status is unique in allowing user-defined values to meet specific business needs, while Payroll and HR Statuses remain locked to maintain consistency. Thus,Bis the correct answer.
