Which statement best describes movement by humans?

• A. Motor vehicle
• B. Public vehicle
• C. Not a motor vehicle
• D. Aircraft

Answer: (C)

Movement by humans is non-motorized locomotion—the person moves themselves without an engine. A motor vehicle is a machine designed to transport people or goods and is propelled by an engine or motor. Since people can walk or run without any engine, their movement isn’t a vehicle, so the description not a motor vehicle fits best. The other options describe engine-powered conveyances (motor vehicle, public vehicle, aircraft) rather than the act of human self-propulsion.
