Which subordinate organization is aligned under the Air Force installation and mission support center (AFIMSC)?

The Air Force Civil Engineering Center (AFCEC) is the correct answer because it is specifically aligned under the Air Force Installation and Mission Support Center (AFIMSC). AFIMSC serves as a hub for various mission support activities within the Air Force, and the Civil Engineering Center plays a critical role in providing comprehensive engineering solutions and support for the installation and operational requirements of the Air Force.

The function of the AFCEC is to oversee and manage a wide range of engineering programs, including infrastructure, environmental management, and facility sustainment. This clear alignment with the goals of AFIMSC ensures that the Air Force maintains resilience and readiness through effective installation support.

While the other organizations listed have important roles within the Air Force, they operate under different structures and do not fall under the AFIMSC's direct oversight. The Air Force Logistics Readiness Center, for instance, focuses on logistics and supply chain management, while the Air Force Personnel Center manages human resources and personnel issues, and the Air Force Medical Service oversees healthcare within the armed forces. Each of these roles is vital but does not directly relate to the mission of the AFIMSC in terms of installation and mission support.
