Answer:
C) The goods are nonconforming because of the perfect tender rule.
Step-by-step explanation:
Under UCC rules, the perfect tender rule applies to contracts where goods are sold, and it states that the seller must comply with the specifications that the buyer required. The perfect tender rule is used for products whose compliance with certain norms is important and vital, e.g. pharmaceutical drugs.
On the other hand, the substantial performance rule may apply to circumstances where the specifications are not that important, and a product close enough is considered sufficient. E.g. a contract for the sale of t-shirts that require a specific type of red might be satisfied by providing red t-shirts even if it wasn't the exact type of red.
