What are the functional categories that comprise the functional areas?

The correct answer identifies the functional categories that collectively represent the core areas of support and operations within the military framework. "Force Sustainment" refers to the ongoing supply and maintenance of personnel and equipment, ensuring that troops are well-equipped and supported during operations. "Operations Support" indicates the efforts related to planning, executing, and supporting military operations, providing essential support to commanders. "Operations Division" encapsulates the structure and strategic direction necessary for maintaining operational effectiveness within various military roles. This alignment of terms accurately reflects the systematic approach to managing military resources and personnel effectively, which is essential for mission success.

By contrast, the other options either mislabel the functional areas or include incorrect terminology. Recognizing the correct classifications is vital for understanding the organization and function of military support systems.
