What should you do if a vehicle's odometer cannot be reset to its previous mileage?

Answer: C — Include an odometer statement saying "not actual" mileage

When the odometer can’t be reset to the prior mileage, you must clearly disclose that the mileage shown is not the actual mileage. This protects buyers from being misled and satisfies odometer disclosure requirements. Setting the reading to zero would be misrepresentation, and a sticker on the door frame isn’t an official disclosure. The proper course is to include an odometer statement that the mileage is not actual, so the buyer understands the true mileage at the time of sale. If the actual mileage is known, it can be provided through the appropriate disclosure process, but the key point is that the not-actual mileage must be stated on the odometer disclosure.
