Briz-M upper stage

Target entity: Briz-M upper stage
Context triple: [Khrunichev State Research and Production Space Center, product, Briz-M upper stage]

• A. Fregat upper stage
  The Fregat upper stage is a Russian space launch vehicle component used to precisely place satellites into various orbits and interplanetary trajectories.
• B. Ablestar upper stage
  The Ablestar upper stage was a liquid-fueled rocket stage developed in the late 1950s–early 1960s to enhance the Thor missile’s capability for placing satellites into orbit and performing precise orbital maneuvers.
• C. Star 48BV upper stage
  The Star 48BV upper stage is a solid-fueled rocket motor used as a high-energy kick stage to boost spacecraft, such as NASA’s Parker Solar Probe, onto their required trajectories.
• D. Centaur upper stage
  The Centaur upper stage is a high-energy rocket stage developed by the United States that pioneered the use of liquid hydrogen and liquid oxygen propellants to boost payloads from low Earth orbit to higher orbits and interplanetary trajectories.
• E. Lockheed Agena upper stage
  The Lockheed Agena upper stage was a versatile rocket stage used extensively during the early U.S. space program as both a satellite booster and maneuverable spacecraft bus for missions including reconnaissance and rendezvous experiments.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
