ITDone is a computer company. It contracts to sell computer hardware systems that will manage BigBox's inventory. The contract provides that the hardware will be delivered in one installment and that BigBox's payment will be due once the hardware is delivered and tested. ITDone delivers and installs 90% of the hardware and informs BigBox that it will do no further work on the project. When BigBox refuses to pay ITDone, ITDone sues BigBox for breach of contract. Assume the contract is governed by the UCC, and not the common law. Choose the best answer:

A.If BigBox argues that ITDone did not complete the contract, its argument will fail, since failing to complete 100% of a contract never excuses a duty to pay.

B. If BigBox argues that ITDone did not complete the contract, its argument will fail, sinceITDone substantially performed the contract.

C. If BigBox argues that ITDone did not complete the project, its argument will succeed, since ITDone did not comply with all of the requirements of the contract.
