Target entity: Lockheed XP-49
Context triple: [Allison V-1710, usedInAircraft, Lockheed XP-49]

• A. Curtiss XP-55 Ascender
  The Curtiss XP-55 Ascender was an experimental World War II–era American fighter prototype notable for its radical canard pusher configuration and unconventional aerodynamic design.
• B. Bell P-59 Airacomet
  The Bell P-59 Airacomet was the first American jet fighter aircraft, serving primarily as a testbed that introduced the U.S. Army Air Forces to jet propulsion during World War II.
• C. Convair XF-92
  The Convair XF-92 was an experimental American delta-wing jet interceptor prototype developed in the late 1940s that served as a pioneering testbed for high-speed delta-wing aircraft design.
• D. Bell XP-77
  The Bell XP-77 was an experimental lightweight American fighter prototype of World War II, designed with wooden construction to conserve strategic materials but ultimately cancelled before mass production.
• E. Lockheed F-80 Shooting Star
  The Lockheed F-80 Shooting Star was one of the first operational jet fighter aircraft of the United States, seeing extensive service in the early Cold War and during the Korean War.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
