Vintage Car Mart Sells Vintage Cars by Auction

Vintage Car Mart sells vintage cars by auction. Alphonso attends one of their auction sales and, carried away by the excitement, is the highest bidder for a vintage car which he has not seen. The car is described as a 1961 Jaguar E-type in British Racing Green and in good running order.
Which of the following statements is most true?

A) If Alphonso fails to sign the written contract at the end of the sale, specific performance will not be available, because only written contracts can be enforced by means of an order for specific performance.
B) If the car is a different colour and lacking essential components in the engine, Vintage Car Marts cannot enforce the contract by means of specific performance because the property has been misdescribed.
C) If the car is a different colour and lacking essential components in the engine, Alphonso cannot enforce the contract by means of specific performance because the property has been misdescribed.
D) Cars can easily be acquired on the open market, so this is not a situation where specific performance would normally be available.
