Administrative law primarily allows for the creation of what type of entities?

Administrative law primarily enables the establishment of public regulatory agencies, which are created to ensure the enforcement and administration of specific statutes and regulations. These agencies are crucial in managing various aspects of public policy, including health, safety, the environment, and economic regulations. They often possess the authority to create rules, enforce compliance, and adjudicate disputes within their designated areas, demonstrating the role that administrative law plays in facilitating governmental functions and addressing public needs.

The other options do not align with the primary focus of administrative law. Judicial courts are part of the judiciary system and are established under constitutional law; legislative bodies are created through legislative processes and are primarily concerned with law-making rather than regulation; and criminal prosecution offices relate to the enforcement of criminal law specifically rather than the broader regulatory framework that administrative law encompasses. Thus, public regulatory agencies are distinctly formed through and regulated by administrative law, making them the correct answer.
