Long Duration Propulsive EELV Secondary Payload Adapter

Target entity: Long Duration Propulsive EELV Secondary Payload Adapter
Context triple: [USSF-67, secondaryPayloadType, Long Duration Propulsive EELV Secondary Payload Adapter]

• A. Inertial Upper Stage
  The Inertial Upper Stage was a two-stage, solid-fueled rocket used primarily with the Space Shuttle and Titan launch vehicles to boost satellites from low Earth orbit to higher orbits such as geostationary transfer orbit.
• B. External Tank
  The External Tank was the large orange-brown fuel tank of NASA’s Space Shuttle, supplying liquid hydrogen and liquid oxygen to the orbiter’s main engines during launch before being jettisoned to burn up in the atmosphere.
• C. Interim Cryogenic Propulsion Stage
  The Interim Cryogenic Propulsion Stage is a liquid hydrogen–liquid oxygen upper stage used on early NASA Space Launch System missions to provide orbital insertion and translunar injection capability before the introduction of a more powerful exploration upper stage.
• D. Exploration Upper Stage
  The Exploration Upper Stage is a powerful second stage designed to enhance NASA’s Space Launch System rocket’s capability to send heavier payloads and crewed missions deeper into space, including to the Moon and beyond.
• E. Agena Target Vehicle
  The Agena Target Vehicle was an unmanned spacecraft used during NASA's Gemini program to practice rendezvous and docking maneuvers in Earth orbit.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
