Marvin Offers to Sell His Lawnmower to Cheryl for $75

Marvin offers to sell his lawnmower to Cheryl for $75 if she pays cash and picks the mower up at his house the following week.Cheryl replies that she would like to buy the mower and thinks $75 is a fair price, but she has no way to transport the mower, so she will buy it for cash if Marvin will have it delivered to her house.In this situation:

A) Cheryl has provided an additional term, which will be construed as a proposal which Marvin can accept or reject.
B) Marvin and Cheryl are considered merchants in relation to the mower, so the delivery of the mower is an additional term which will become part of the contract unless Marvin objects within a reasonable time.
C) the delivery of the mower is a different term from that in the offer, and it generally will not become part of the contract unless Marvin specifically agrees to it.
D) courts would all agree that the different delivery terms cancel each other out and the Code would provide the missing term.
