Seller put an ad in the paper saying he would sell his land for a minimum of $50,000. Buyer wrote him expressing interest in purchasing the land. Seller e-mailed Buyer telling her she needed to act fast if she was interested, because he had other offers for the property. The next communication from Buyer to Seller was an e-mail from Buyer stating that she had opened escrow with instructions to the escrow agent to pay Seller $50,000 upon receipt of good title to the property. Seller wrote back that he had already sold the property to another for $60,000. If Buyer sued Seller for breach of contract, which of the following is true?
(A) Seller should prevail because Seller revoked his offer when he told Buyer she had to act fast.
(B) Seller should prevail because they had not entered into a contract.
(C) Buyer should prevail because Seller breached an enforceable contract to sell the property for $50,000.
(D) Buyer should prevail because she materially relied on Seller's offer when she opened escrow.
