Final answer:
A Public Relations Officer is not normally eligible to be appointed as a Certifying Officer since their role focuses on communications rather than financial certifications. Option D
Step-by-step explanation:
The U.S. Office of Personnel Management categorizes jobs to ensure a structured and efficient government workforce. Among the personnel listed, a Public Relations Officer is not normally eligible for appointment as a Certifying Officer. Certifying Officers are responsible for certifying the availability of funds for government transactions.
Finance Officers and Procurement Specialists are commonly associated with managing and authorizing expenses, hence they are more likely to fit the profile for such responsibilities.
An Administrative Assistant, depending on their level of financial responsibility, could potentially be eligible, but the title alone does not generally confer the necessary authority. In contrast, Public Relations Officers typically focus on communications and media relations and would not usually be involved in financial certifications. Option D
