Triple

Target entity: Rolls-Royce B60 petrol engine
Context triple: [Ferret armoured car, engine, Rolls-Royce B60 petrol engine]

• A. Rolls-Royce Meteor petrol engine
  The Rolls-Royce Meteor petrol engine was a powerful British V12 tank engine derived from the Merlin aircraft engine, widely used to propel World War II armored vehicles such as the Cromwell.
• B. Rolls-Royce K60 multi-fuel engine
  The Rolls-Royce K60 is a British-designed, compact, opposed-piston multi-fuel diesel engine widely used to power Cold War–era armored fighting vehicles.
• C. Rolls-Royce Kestrel V12 engine
  The Rolls-Royce Kestrel V12 engine is a British liquid-cooled aircraft piston engine of the interwar period, widely used in RAF fighters and other military aircraft as an important step in Rolls-Royce’s development of high-performance aero engines.
• D. Rolls-Royce R engine
  The Rolls-Royce R engine was a high-performance British aero engine developed in the late 1920s that powered record-breaking racing seaplanes and laid the technological groundwork for later Rolls-Royce engines like the Merlin.
• E. Rolls-Royce Kestrel engine
  The Rolls-Royce Kestrel engine is a British liquid-cooled V-12 aircraft piston engine of the interwar period that powered numerous notable military aircraft and helped establish Rolls-Royce’s reputation in aero engine design.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
