Triple

Target class: power and propulsion module
Context triple: [PPE (Power and Propulsion Element), instanceOf, power and propulsion module]

• A. spacecraft power system
  A spacecraft power system is the integrated set of components and subsystems that generate, store, condition, and distribute electrical energy to support all spacecraft functions throughout its mission.
• B. astronaut propulsion system
  An astronaut propulsion system is a compact, controllable device that enables astronauts to maneuver independently in space by generating thrust through expelled propellant or alternative reaction-mass technologies.
• C. spacecraft service module chosen
  A spacecraft service module is the section of a spacecraft that houses and provides essential support systems—such as propulsion, power, thermal control, and consumables—to enable and sustain the operation of the crew or payload module.
• D. nuclear pulse propulsion system
  A nuclear pulse propulsion system is a spacecraft propulsion method that generates thrust by detonating a series of small nuclear explosives behind the vehicle and transferring the resulting impulse through a robust pusher plate and shock-absorbing structure.
• E. ablative thermal protection system
  An ablative thermal protection system is a heat shield that protects a spacecraft by sacrificially charring, melting, and eroding material to absorb and carry away extreme reentry heat.
• F. None of above.
