Delta rocket

Target entity: Delta rocket
Context triple: [Geostationary Operational Environmental Satellite program, firstLaunchVehicle, Delta rocket]

• A. Falcon 1 rocket
  Falcon 1 rocket is a small, privately developed orbital launch vehicle created by SpaceX that became the first privately built liquid-fueled rocket to reach orbit.
• B. Epsilon launch vehicle
  The Epsilon launch vehicle is a Japanese solid-fuel rocket designed for cost-effective, small satellite launches into orbit.
• C. R-1 rocket
  The R-1 rocket was an early Soviet ballistic missile and research rocket developed after World War II as a near-copy of Germany’s V-2, serving as a foundation for later Soviet rocketry.
• D. Proton rocket
  The Proton rocket is a heavy-lift Russian expendable launch vehicle widely used to place large payloads, including space station modules and communications satellites, into orbit.
• E. LC-39B
  LC-39B is a launch pad at NASA’s Kennedy Space Center that has supported major crewed and uncrewed space missions, including Space Shuttle flights and later Space Launch System operations.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
