Define “motor vehicle”:
- A vehicle propelled by a diesel engine only
- A vehicle propelled by a gasoline engine only.
- Correct answer: A vehicle, propelled by any power or mechanical means.
- A vehicle with at least two wheels.
Why this is the answer
The correct answer in the official bank: A vehicle, propelled by any power or mechanical means.
A motor vehicle is defined by how it is propelled, not by its fuel. Any vehicle driven by mechanical power counts, whether its engine runs on gasoline, diesel, electricity or anything else, so limiting it to one fuel type is wrong. The number of wheels doesn't decide it either: an ordinary bicycle has two wheels but is not mechanically propelled.
