Final answer:
The correct answer to the question on vehicle disclosure requirements is 'All of the above,' meaning sellers must inform buyers of prior registration in other regions, non-functioning ABS, and the need for air conditioning repairs.
Step-by-step explanation:
The question deals with the disclosure requirements when selling a vehicle, focusing on what sellers must reveal to potential buyers. The correct answer to which facts about a vehicle must be disclosed is d) All of the above. This means that sellers are required to disclose if a vehicle was previously registered in another province, state, or country; if the vehicle's anti-lock braking system is not functioning; and if the vehicle's air conditioning system requires repair. These disclosures are typically mandated by law to ensure that buyers are fully informed about the condition of the vehicle they are purchasing, which is critical for safety, legal, and financial reasons.
