Answer:
David wants to buy a bike or a scooter.
Explanation:
The original sentence "David wants to buy a bike. Or a scooter." so the best revision of that sentece would be the first option David wants to buy a bike or a scooter, because its not necessary to put the point to separate the sentence "Or the scooter" from the rest of the sentence, they can go along together, so the best revision from the options would be David wants to buy a bike or a scooter.
