• A. International Space Station truss segment
  An International Space Station truss segment is a structural module that forms part of the station’s backbone, supporting solar arrays, radiators, and utilities while providing attachment points and routing for power, data, and thermal control systems.
• B. modular spacecraft chosen
  A modular spacecraft is a reconfigurable space vehicle composed of interchangeable, standardized modules that can be assembled, upgraded, or replaced to support different missions and functions.
• C. in-situ resource utilization technology demonstrator
  An in-situ resource utilization technology demonstrator is a prototype system designed to test and validate methods for extracting, processing, and using local materials (such as lunar or Martian regolith) to support space missions and reduce dependence on Earth-supplied resources.
• D. Long Duration Propulsive EELV Secondary Payload Adapter mission
  A Long Duration Propulsive EELV Secondary Payload Adapter mission is a spaceflight that uses a propulsive ESPA ring on an Evolved Expendable Launch Vehicle to carry and operate secondary payloads for extended periods in space, providing independent maneuvering and mission flexibility separate from the primary payload.
• E. Saturn V mobile launcher
  The Saturn V mobile launcher was a massive, self-contained launch platform and service structure that transported, supported, and provided umbilical connections to the Saturn V rocket from assembly to liftoff.
• F. None of above.
