In which situation does military installation administration typically remain with the contracting office?

Military installation administration typically remaining with the contracting office in the context of option D is grounded in the specific nature of military operations and the oversight they require. When dealing with military installations, the contracting office holds a significant role in ensuring compliance with military standards, security protocols, and ongoing operational requirements. This close oversight is crucial because military installations often have unique missions, priorities, and regulations that need to be adhered to, thus making centralized administrative control essential for effective contract management.

In this situation, the contracting office is better positioned to coordinate resources, manage relationships, and enforce regulations necessary for maintaining the integrity and functionality of military installations. This control ensures that all operations related to contracting align with the military’s strategic goals and operational readiness, maintaining a level of oversight that is not as necessary in other contracting environments.

Other choices focus on situational factors such as the location of the contractor or the general nature of contracts which may not specifically pertain to military installations and the unique oversight required for them. Thus, it's the specific context of military installations that justifies the administration by the contracting office.
