RP-1

Target entity: RP-1
Context triple: [Kestrel, fuel, RP-1]

• A. RL10
  RL10 is a family of high-performance, liquid hydrogen–liquid oxygen cryogenic rocket engines developed by Aerojet Rocketdyne and widely used on U.S. upper stages such as Centaur and Delta IV.
• B. Falcon 9 rocket
  The Falcon 9 rocket is a partially reusable, two-stage orbital launch vehicle developed by SpaceX that has revolutionized commercial spaceflight through frequent, cost-effective missions and routine booster landings.
• C. BFR
  BFR, now known as SpaceX's Starship launch system, is a fully reusable, next-generation spacecraft and rocket designed for missions to Earth orbit, the Moon, Mars, and beyond.
• D. Falcon rocket family
  The Falcon rocket family is a series of partially reusable launch vehicles developed by SpaceX to provide cost-effective access to space for satellites, cargo, and crew.
• E. Curtiss-Wright XLR25 rocket engine
  The Curtiss-Wright XLR25 was an American liquid-fueled rocket engine developed in the 1950s to power high-speed experimental research aircraft such as the Bell X-2.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
