If the prelease agreement is canceled within the specified period, what must the dealer provide to the customer?

Answer: A — Full refund of any fees paid

If the prelease agreement is canceled, the dealer is obligated to provide the customer with a full refund of any fees paid. This is because the agreement was not fulfilled and the dealer cannot keep any payment or fees without providing the promised services. Option B is incorrect because a written notification may not necessarily result in a refund for the customer. Option C is incorrect because even though the contract may not be binding, the dealer still has a responsibility to refund any fees paid. Option D is incorrect because a new prelease agreement may not be agreed upon or necessary in this situation.
