Centaur upper stage

Target entity: Centaur upper stage
Context triple: [RL10, usedOn, Centaur upper stage]

• A. Starship upper stage
  The Starship upper stage is the fully reusable spacecraft component of SpaceX’s Starship launch system, designed to carry crew and cargo to Earth orbit, the Moon, Mars, and beyond.
• B. Atlas-Centaur
  Atlas-Centaur was an American expendable launch vehicle family that combined an Atlas booster with a high-energy Centaur upper stage to send payloads, including early interplanetary probes, into space.
• C. Titan IIIE-Centaur
  Titan IIIE-Centaur was a U.S. expendable launch vehicle that combined a Titan III booster with a high-energy Centaur upper stage to send deep-space probes such as Voyager 2 on interplanetary trajectories.
• D. Vulcan Centaur
  Vulcan Centaur is United Launch Alliance’s next-generation, two-stage heavy-lift rocket designed to replace Atlas V and Delta IV for a wide range of commercial, government, and deep-space missions.
• E. Exploration Upper Stage
  The Exploration Upper Stage is a powerful second stage designed to enhance NASA’s Space Launch System rocket’s capability to send heavier payloads and crewed missions deeper into space, including to the Moon and beyond.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
