Answer:
Option A. The UCC because it is a mixed contract predominately for the sale of goods.

The Universal Commercial Code deals with all the transactions that are connected with the transaction of goods that have physical existence. If the transaction also includes the share of services which forms part of contract and are minor in amount then it is also governed by the UCC otherwise it is out of the scope of the Universal Commercial Code.

Furthermore, if the mixed contract was predominantly for services then it is out of the scope of UCC. So the right answer is option A.
