On April 1, Elizabeth offered to sell Thomas the last puppy from the litter her dog had just birthed for $600. Thomas wanted some time to think about it, but Elizabeth knew her neighbor Amanda was dying to buy the puppy, and Elizabeth really needed the money. Because Elizabeth and Thomas had been best friends for a long time, Elizabeth told Thomas she would keep her offer open until April 8, in exchange for $5 from Thomas. Thomas gave Elizabeth the $5 and went home to think about the deal. Thereafter, Amanda gave Elizabeth $600 in cash for the puppy "just in case" Thomas did not want the puppy. After a long week of indecision about the responsibility of owning a puppy, Thomas woke up on the morning of April 8 and knew he had to have the puppy. He called Elizabeth immediately to tell her his decision, but she had not paid her phone bill and her line was cut off. Instead, Thomas wrote a check to Elizabeth for $600 and put it in a stamped envelope along with a note that he was accepting the offer to purchase the puppy. The envelope was properly stamped and addressed, and Thomas dropped the envelope in the mailbox at 10:00 p.m. on April 8. The note and check were not received by Elizabeth until April 10. When Elizabeth had not received the letter, or otherwise heard, from Thomas on April 8, she told Elizabeth the puppy was hers on April 9. 24.
Who owns the puppy in a jurisdiction that follows the Restatement 2d of Contracts?
(A) Thomas, because he had a valid option contract with Elizabeth and effectively accepted Elizabeth's offer to sell the puppy for $600 because, under the "mailbox rule," acceptances are effective upon dispatch.
(B) Amanda, because oral option contracts are unenforceable.
(C) Amanda, because Elizabeth sold the puppy to Amanda on April 9th before receiving Thomas's check.
(D) Elizabeth, because the sale of goods priced $500 or more must be in writing or it is void.
