Explain how the result in Question 3 might change if the U.S. Electronics form contained the following provisions:

a. ‘‘The seller's acceptance of the purchase order to which this acknowledgment responds is expressly made conditional on the buyer's assent to any or different terms contained in this acknowledgment.''

b. ‘‘The seller's acceptance of the purchase order is subject to the terms and conditions on the face and reverse side hereof, which the buyer accepts by accepting the goods described herein.''

c. ‘‘The seller's terms govern this agreement-this acknowledgment merely constitutes a counteroffer.''
