Answer :
Final answer:
A buyer can accept a nonconforming installment without losing the right to reject future installments, an exception to the perfect tender rule. This does not relate to the battle of the forms, course of performance, or course of dealing, which addresses different aspects of commercial contract interpretation. The correct answer is a) The perfect tender rule
Explanation:
The question deals with the circumstances under which a buyer can accept part of a contract (one installment) without waiving the right to reject future nonconforming installments. This is an exception to the perfect tender rule, which generally requires that the goods and performance must exactly meet the contract terms. If the buyer accepts a nonconforming installment without expressly reserving the right to reject future deliveries, they are generally considered to have accepted the goods. However, the Uniform Commercial Code (UCC) provides for an exception where the buyer can accept a nonconforming installment without prejudice to the right to reject future shipments. This does not generally apply to the battle of the forms, which pertains to the acceptance and negotiation of different terms between commercial parties. Nor is it about the course of performance or course of dealing, which concerns the interpretation of ambiguous contract terms based on past business between the parties or the routine manner in which they conduct transactions.
