Samson Electronics sent the following signed communication to Boyston Systems, Inc. on November 13: "For sale - Dell Exceleron System Computer and Server - Model X2455 - $10,500. Let us know if you want it." On November 15 Boyston sent the following communication back to Samson (which communication was received by Samson shortly after it was sent): "We will take the Computer at $8,500, but no more than that." Having heard nothing from Samson, a few days later Boyston sent the following communication to Boyston on November 17: "It appears that you are firm on your price, we'll take it at the $10,500 price you offered." Samson had already sold the computer and server to another party. Boyston is upset and claims that it has a contract with Samson to purchase the computer and server. Samson disagrees. Which of the following statements is correct? O A. A contract was formed on November 17 when Boyston sent its communication to Samson B. A contract was formed and the price of the computer will be $8,500 because Samson did not promptly respond to Boyston's November 15 communication. O C. A contract was formed on November 17 because Boyston's November 15 communication had no legal effect. O D. No contract was formed between the parties because of Boyston's November 15 communication. O E. Because Samson is a merchant, it had an obligation to keep its November 15 offer open for a reasonable period of time.
