What document governs local matters under municipal law?

The correct answer is "Ordinance" because it specifically refers to laws enacted by a municipal authority or local government to regulate matters within its jurisdiction. Ordinances are designed to address the unique needs and issues of local communities, covering a wide range of topics such as zoning laws, traffic regulations, noise control, and other local governance issues.

While statutes are laws enacted at the state or federal level, regulations are detailed rules created by administrative agencies to implement statutes, and resolutions are formal statements or decisions made by a governing body that do not have the binding force of law like ordinances do. Therefore, ordinances are the governing documents that allow municipalities to maintain order and manage local governance effectively.
