Under what condition can the seller disclose that the odometer reading reflects the "actual" mileage?
Answer: C — If the malfunction occurred within 30 days and the mileage traveled since the malfunction is reasonably accurate
The other options, A, B, and D, are incorrect because they do not directly address the specific condition under which the seller can disclose the "actual" mileage. Option A only mentions that the odometer has not been tampered with, but it does not specify any timeframe or reason for the disclosure. Option B only involves the confirmation of the original owner, but it does not establish any condition for disclosure. Option D only mentions mileage within 500 miles of the original reading, but it does not mention any specific condition for disclosure.
