What are the primary military departments in the U.S. Armed Forces?

• A. Navy excluding Marine Corps
• B. Navy including Space Force
• C. Army, Navy (including Marine Corps), and Air Force (including Space Force)
• D. Space Force

Answer: (C)

The main idea is that the United States organizes its senior military departments into three primary ones: the Army, the Navy, and the Air Force. The Marines aren’t a separate department; they’re part of the Navy, and the Space Force is part of the Air Force. So the full, accurate description reflects the Army, Navy (including the Marine Corps), and the Air Force (including the Space Force). The other options misstate the organizational structure by excluding the Marines, placing Space Force under the Navy, or listing Space Force alone.
