Phrase: X-24 | Statement: [Rolls-Royce Vulture, configuration, X-24]

Target entity: X-24
Context triple: [Rolls-Royce Vulture, configuration, X-24]

• A. 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.
• B. Northrop X-21
  The Northrop X-21 was an experimental U.S. jet aircraft of the 1960s designed to test laminar-flow control technology for improved aerodynamic efficiency.
• C. 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.
• D. Bell X-15
  The Bell X-15 was a rocket-powered experimental aircraft that set speed and altitude records in the 1960s and contributed crucial data to the development of crewed spaceflight and high-speed aeronautics.
• E. Bell X-2
  The Bell X-2 was a rocket-powered experimental research aircraft developed in the 1950s to investigate flight characteristics at extremely high speeds and altitudes, contributing crucial data to early supersonic and space-era aeronautics.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity.
