Which type of rule is developed by various government or government-authorized organizations to implement a law that has been passed by a government body?

The correct answer is regulation, which refers to specific rules or directives created by government agencies to implement and enforce laws that have been passed by legislative bodies. Regulations provide the detailed framework within which the law operates and ensure that the objectives of the law are met. They can cover a wide range of areas, including safety standards, environmental protections, and operational guidelines for various industries.

In contrast, a policy is a broader statement of principles or goals that guide decisions and actions but does not have the force of law. An ordinance is a local law enacted by a municipal authority, often more focused on specific local issues, while an act is legislation passed by the legislative body that sets out the legal requirements or standards but requires regulation for enforcement and implementation. Understanding the distinction between these terms is crucial for grasping how laws function and are applied in practice.
