Contract law

QUESTION 9 Buyer, a merchant, makes a written offer to buy certain cattle from Seller, a merchant located in Wyoming. Buyer's offer contains 5 specific terms. Seller responds to Buyer with a writing by which he accepts all 5 terms but includes a 6 term in his acceptance: "This transaction will be governed by Wyoming law." Assume that Buyer does not respond further to the Seller and that 10 days elapse after the Buyer receives the acceptance. What is the legal effect of this communication by Seller? a. A contract between the parties has been formed with regard to the 5 terms on which there is agreement; the 6th term has no legal effect. Ob. There is no contract formed between the parties because of the Seller's inclusion of the 6th term. c. A contract between the parties has been formed between the parties that includes all 6 terms. d. A contract between the parties has been formed with regard to the 5 terms on which there is agreement; whether the 6th term will become part of the contract will depend on whether the 6th term materially alters the contract between the parties
