Which of the following is a source of contract law?

Contract law is primarily derived from legislation, which includes statutes and regulations enacted by governmental bodies that specifically address the formation, enforcement, and interpretation of contracts. Legislative sources provide a framework within which contracts must operate, establishing essential principles such as offer, acceptance, consideration, and the capacity to contract.

In addition, legislation can include the Uniform Commercial Code (UCC), which governs commercial transactions in the United States, enhancing uniformity and predictability in contract law for businesses. Therefore, identifying legislation as a source of contract law reflects an understanding of how laws interplay with business practices and personal agreements, shaping the legal landscape in which contracts function.

Other options, such as family law, local ordinances, and criminal law, do not typically govern contract law directly. Family law pertains to domestic relations, local ordinances are specific regulations imposed by local governments often related to zoning and land use, and criminal law addresses offenses against the state rather than private agreements between parties.
