Phrase: Bell X-1-2 | Statement: [Bell X-1E, airframeOrigin, Bell X-1-2]

Target entity: Bell X-1-2
Context triple: [Bell X-1E, airframeOrigin, Bell X-1-2]

• A. Bell X-1B
  The Bell X-1B was an advanced variant of the original Bell X-1 rocket-powered research aircraft, used primarily to investigate high-speed aerodynamic heating and stability at transonic and supersonic speeds.
• B. Bell X-1A
  The Bell X-1A was an experimental rocket-powered research aircraft developed in the early 1950s to investigate high-speed, high-altitude flight beyond the capabilities of the original Bell X-1.
• C. Bell X-1E
  The Bell X-1E was a late, highly modified variant of the pioneering X-1 rocket research aircraft, used by the U.S. to investigate high-speed transonic and supersonic flight aerodynamics in the 1950s.
• D. Bell X-1C
  The Bell X-1C was a planned but never completed advanced variant of the Bell X-1 rocket-powered research aircraft, intended for high-speed military weapons testing.
• E. Bell X-1D
  The Bell X-1D was an experimental rocket-powered research aircraft in the X-1 series, built to extend high-speed flight testing beyond the capabilities of the original Bell X-1.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
