Which component operates under the Naval command structure?

The correct answer highlights the fact that the Naval Special Warfare Command (NSWC/WARCOM) operates within the Naval command structure, which is integral to the United States Navy. This command is specifically responsible for overseeing Naval Special Warfare forces and missions, including SEAL teams and Special Warfare Combatant-craft crews. As a component of the Navy, it is directly integrated into the Naval command hierarchy and works collaboratively with other naval units and operations.

Other components like the Air Force Special Operations Command, Marine Corps Forces Special Operations Command, and US Army Special Operations Command fall under their respective branches of the military—Air Force, Marine Corps, and Army. These commands operate within their distinct organizational structures and are focused on their branch-specific missions. This is why they do not fall under the same command structure as Naval forces, distinguishing NSWC/WARCOM's unique position within the Navy's operational command framework.
