Context triple: [Missions of Opportunity, instanceOf, relatively low-cost space mission category]

• A. small-lift launch vehicle
  A small-lift launch vehicle is a relatively low-mass rocket system designed to place small payloads, typically under a few thousand kilograms, into Earth orbit or suborbital trajectories.
• B. space mission rideshare platform
  A space mission rideshare platform is a digital marketplace that connects satellite operators and payload customers with available launch capacity on rockets, enabling shared missions, cost savings, and streamlined logistics for accessing space.
• C. medium-lift launch vehicle
  A medium-lift launch vehicle is a rocket system designed to place a moderate payload mass—typically several tons—into low Earth orbit or higher orbits, balancing performance and cost between small and heavy-lift launchers.
• D. expendable launch vehicle family
  An expendable launch vehicle family is a series of related, single-use rockets designed to carry payloads into space and then be discarded after each mission.
• E. space mission
  A space mission is a planned and coordinated endeavor to send spacecraft, instruments, or humans beyond Earth's atmosphere to achieve specific scientific, exploratory, commercial, or technological objectives.
• F. None of above. chosen
