Who should be shown the prior owner's odometer statement?

Answer: B — All prospective customers before sale

The correct answer is B because the prior owner's odometer statement provides important information about the vehicle's mileage and can influence a potential buyer's decision. Showing this statement to all prospective customers before the sale is important in ensuring transparency and honesty in the transaction. Options A, C, and D are incorrect because they do not involve sharing the statement with the potential buyers, which can lead to an unfair or misleading sale.
