Which of These Is Not a Rule Relating to the Passing

Which of these is not a rule relating to the passing of title to goods?

A) If there is an unconditional contract for the sale of specific goods in a deliverable state, the property in the goods passes to the buyer when the contract is made, and it is immaterial whether the time of payment, the time of delivery or both are postponed.
B) Where the seller must do something to the goods to put them in a deliverable state, title will not pass until the seller does whatever is necessary to put the goods in a deliverable state and notifies the buyer that the goods are now ready for delivery.
C) If there is a contract for the sale of specific goods in a deliverable state, but where the seller must weigh, measure, test, or do something to ascertain the price, the property in the goods does not pass until the act is done. Notice to the buyer is not required.
D) Where there is a contract for the sale of goods "on approval" or with return privileges the title will pass if the buyer, on receipt of the goods, does anything to signify his or her acceptance or approval of the goods, or the adoption of the contract.
E) As soon as the goods ordered by description are produced and in a deliverable state and are unconditionally appropriated to the contract, either by the seller or by the buyer, the property in the goods will pass.
