Why have you used quotation marks in your sentences?
Did you come by car, autorickhaw, motorcycle, bicycle or boat?
Did you come on a bus, plane, ship or train?
It depends on what you're actually asking us to look at. If you're planning to ask someone "Did you come by car, autorickshaw, motorcycle, cycle or boat?" then you should not put quotation marks round each form of transport.
If you're asking us if it's possible to say "Did you come by car?", "Did you come by autorickshaw?", "Did you come by motorcycle?", "Did you come by bicycle?" and "Did you come by boat?" then that is exactly how you should lay it out. List each exact question you are unsure about and we can comment on each one.
