Saturn rocket family

Target entity: Saturn rocket family
Context triple: [Saturn I, partOf, Saturn rocket family]

• A. Saturn IB
  Saturn IB was a two-stage American launch vehicle used by NASA in the 1960s and early 1970s to test Apollo spacecraft in Earth orbit and support missions such as Apollo–Soyuz.
• B. Saturn V
  Saturn V was a powerful American heavy-lift launch vehicle used during the Apollo and Skylab programs to send astronauts and payloads into space, including missions to the Moon.
• C. Saturn I
  Saturn I was an early American expendable launch vehicle developed by NASA that served as a precursor to the more powerful Saturn IB and Saturn V rockets used in the Apollo program.
• D. SM-65 Atlas
  The SM-65 Atlas was the United States’ first operational intercontinental ballistic missile, later adapted as a pioneering space launch vehicle in the early space program.
• E. Saturn V S-II second stage
  The Saturn V S-II second stage was the liquid hydrogen–fueled second stage of NASA’s Saturn V Moon rocket, providing the crucial mid-ascent propulsion that enabled Apollo missions to reach Earth orbit and proceed toward the Moon.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
