Rolls-Royce Olympus turbojet

Target entity: Rolls-Royce Olympus turbojet
Context triple: [Avro Vulcan, powerplant, Rolls-Royce Olympus turbojet]

• A. Rolls-Royce Pegasus turbofan
  The Rolls-Royce Pegasus turbofan is a unique vectored-thrust jet engine that enables vertical and short takeoff and landing (V/STOL) capability in aircraft such as the Harrier family.
• B. Rolls-Royce Nene engine
  The Rolls-Royce Nene engine is a pioneering late-1940s British centrifugal-flow turbojet whose powerful, compact design significantly advanced early jet aircraft performance and was widely exported and copied worldwide.
• C. Rolls-Royce Avon engine
  The Rolls-Royce Avon engine is a pioneering British axial-flow turbojet developed in the late 1940s that powered numerous military and civilian aircraft, including early jet airliners and fighters.
• D. Rolls-Royce Adour turbofan
  The Rolls-Royce Adour is a family of low-bypass turbofan engines developed for military trainer and light attack aircraft, noted for their reliability and widespread use in jets such as the SEPECAT Jaguar and BAE Systems Hawk.
• E. Rolls-Royce Conway engine
  The Rolls-Royce Conway engine was the world’s first production turbofan jet engine, pioneering a more efficient generation of jet propulsion for commercial and military aircraft in the mid-20th century.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
