Full Detailed in Depth Explanation:

In Oracle HCM Cloud, aPerson IDis a unique identifier assigned to individuals within the system who have a person record. The types of people assigned Person IDs include:

Employees: Full-time or part-time workers with an employment relationship.

Contingent Workers: Temporary or contract workers.

Non-Workers: Individuals like retirees or external contacts with a person record but no active work relationship.

Pending Workers: Individuals hired but not yet started (e.g., future-dated hires).

Worker Contacts: Emergency contacts or dependents linked to a worker’s record, who also receive a Person ID for tracking purposes.

Option A omits Pending Workers and Worker Contacts, which are included in the system’s person model. Option C misses Worker Contacts, who are explicitly assigned Person IDs to manage relationships. Option B is the most comprehensive, aligning with Oracle’s definition of person records in the "Person Management" guide, makingBthe correct answer.
