Office Plus,an office supply store,ordered 600 blank CDs from Curtis Co.,a manufacturer of computer products.Office Plus placed the order using a preprinted purchase order form;Curtis acknowledged the order by sending a preprinted acceptance form back to Office Plus.Unlike Office Plus' form which says nothing about packaging,Curtis's form specifies that the CDs will be packaged with 10 per box,30 boxes per case.Which statement is correct?

A) The UCC does not cover CDs.
B) Curtis's packaging term is a different term which materially changes the offer. There is no contract.
C) Curtis's packaging term is a nonmaterial additional term and therefore is part of the contract unless Office Plus promptly objects to the term.
D) The UCC does not cover the contract because both parties are merchants.
