XP-1 (prototype designation)

Target entity: XP-1 (prototype designation)
Context triple: [Kawasaki P-1, developmentCode, XP-1 (prototype designation)]

• A. XF-108 Rapier (prototype)
  The XF-108 Rapier was a proposed long-range, high-speed interceptor aircraft developed by North American Aviation for the U.S. Air Force during the Cold War but canceled before reaching production.
• B. XP-72 prototype fighter
  The XP-72 prototype fighter was an advanced, high-performance American World War II-era interceptor developed by Republic Aviation as a potential successor to the P-47 Thunderbolt.
• C. X-10
  X-10 is the project code name for the Clinton Pile, an early nuclear reactor facility associated with the Manhattan Project.
• D. X-20
  X-20 was an experimental U.S. Air Force spaceplane project from the early Cold War era intended to test reusable, piloted orbital and suborbital flight before being canceled in the 1960s.
• E. Republic XF-103
  The Republic XF-103 was an experimental American Cold War–era interceptor aircraft project intended to achieve very high supersonic speeds using advanced materials and propulsion, but it was cancelled before a prototype was completed.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
