In Oracle HCM, worker numbers are defined as unique identifiers that represent distinct work relationships for individuals within an organization. This means that each worker number is associated with a specific relationship an individual has with the organization, such as full-time employment, part-time employment, contract work, etc. By focusing on unique work relationships, worker numbers help in managing various employment types and ensuring that each worker's details are correctly associated with their specific role and employment status.

The importance of worker numbers lies in their role in tracking and managing workforce data accurately, which is critical for HR functions like payroll, performance management, and compliance. With this approach, organizations can maintain clarity in their employment records and effectively manage human resources across different roles and arrangements.

In contrast, while associations with person numbers and uniqueness across enterprises are considerations in broader employee management and identification, the defining characteristic of worker numbers specifically relates to their linkage to unique work relationships within the organization. This specialized focus is what makes option B the correct choice.
