Final answer:
The correct authority to use for coding the SF-50 when utilizing delegated examining authority is OPM.
Step-by-step explanation:
The correct authority to be used for coding the SF-50 when utilizing delegated examining authority is OPM (Option 3).
OPM stands for the Office of Personnel Management, which is an independent agency of the United States federal government that manages the civil service of the federal government. It plays a central role in ensuring the efficiency and effectiveness of the federal workforce.
Delegated examining authority refers to the authority given to individual agencies to make personnel decisions, such as hiring, based on their own needs and priorities, rather than going through a centralized personnel system. By using the coding authority of OPM, agencies can accurately document and track personnel actions, such as promotions or changes in employment status, on the SF-50 form.
