Answer:
c. The buyer did not have the right to cancel the second shipment, because the defects in the first shipment did not substantially impair the value of the entire contract.
Step-by-step explanation:
In this case, it involves the installment contract. It means that the contract requires deliveries in two different lots and also sale of the goods. Therefore under the Article 2 of the Uniform Commercial Code, the buyer may wish to declare total breach of the installment contract, if the defects substantially impairs the entire contract's value.
In the context, the manufacturer corrected the first defected shipment of stain. The manufacturer offered to cure the defective first shipment to the hardware owner. Thus the first shipment's defect in stain does not impair the whole contract's value.
Hence the correct option is (c).
