On May 1, Ohner telegraphed Byer, "Will sell you any or all of the lots in Grover subdivision at $5,000 each. Details will follow in letter." The letter contained all the necessary details concerning terms of payment, insurance, mortgages, etc., and provided, "This offer remains open until June 1." On May 2, after he had received the telegram but before he had received the letter, Byer telegraphed Ohner, "Accept your offer with respect to lot 101." Both parties knew that there were 50 lots in the Grove subdivision and that they were numbered 101 through 150.""For this question only, assume that on May 5 Ohner telephoned Byer to say that he had sold lots 102 through 150 to someone else on May 4, and that Byer thereafter telegraphed Ohner, "Will take the rest of the lots." Assume further that there is no controlling statute. In an action by Byer against Ohner for breach of contract, Byer probably will
succeed, because Ohner had promised him that the offer would remain open until June 1.  succeed, because Ohner's attempted revocation was by telephone.  not succeed, because Byer's power of acceptance was terminated by Ohner's sale of the lots to another party.  not succeed, because Byer's power of acceptance was terminated by an effective revocation
