When Article 2 is silent on an issue of sales contract formation or interpretation and there is no state statutory law in place on that matter, which law applies?

A) The common law rules
B) The civil law rules
C) Federal common law
D) Federal statutory law
E) The Uniform Sales Act

When Article 2 of the Uniform Commercial Code (UCC), which governs sales of goods, does not address a specific issue related to sales contract formation or interpretation, and there is no applicable state statutory law, the common law rules apply. The common law of contracts serves as the default system of rules in such cases.
