Which three branches make up the Australian Defence Force?

• A. Army, Navy, Air Force
• B. Army, Navy, Coast Guard
• C. Navy, Air Force, Marines
• D. Air Force, Space Force, Army

Answer: (A)

The question tests how the Australian Defence Force is organized into its core service components. The Defence Force is made up of three branches: the Army, the Navy, and the Air Force. Each branch has a distinct role—Army for land operations, Navy for maritime duties, and Air Force for air (and related space) operations. The other options include forces that aren’t separate branches within Australia’s defence structure—there is no Coast Guard as a military service in the ADF, no Marine Corps as a standalone branch, and no Space Force as a separate Australian service. Therefore, the combination that represents the three branches of the Australian Defence Force is Army, Navy, and Air Force.
