• A. cable car system
  A cable car system is a transportation network in which vehicles are pulled by continuously moving cables, typically used to move people or goods along steep or inaccessible routes such as mountainsides or urban hills.
• B. expendable launch system
  An expendable launch system is a type of launch vehicle designed for a single use, where major components are not recovered after delivering payloads such as satellites or spacecraft into orbit or on a trajectory.
• C. fully reusable launch system
  A fully reusable launch system is a space launch architecture in which all major components (such as boosters, upper stages, and spacecraft) are recovered, refurbished, and flown again, minimizing expendable hardware and reducing per-launch costs.
• D. liquid-cooled aircraft engine
  A liquid-cooled aircraft engine is a piston or reciprocating powerplant that uses a circulating liquid coolant, typically water or glycol, to absorb and dissipate heat from the engine cylinders and heads, enabling efficient temperature control and reliable operation in flight.
• E. light rail vehicle
  A light rail vehicle is a rail-based transit vehicle designed for urban and suburban passenger service, typically operating on dedicated or shared tracks with frequent stops and moderate capacity.
• F. None of above. chosen
