What type of public law covers legal principles that apply to government agencies?

The correct choice focuses on administrative law, which is specifically designed to govern the activities of government agencies. This area of law provides the framework for creating, enforcing, and challenging regulations issued by government bodies.

Administrative law ensures that government agencies operate within the scope of their authority, follow fair procedures, and are accountable to the public. It encompasses rules and regulations regarding how agencies function, including regulatory processes, adjudication procedures, and enforcement of agency rules.

In contrast, criminal law deals with offenses against the state or public and establishes punishments for violations. Constitutional law pertains to the interpretation and application of the constitution and addresses the structure of government, individual rights, and the relationship between various entities in government. Civil law generally concerns disputes between private parties, which are typically resolved through compensation rather than sanctions imposed by the government.

Thus, the principal focus of administrative law on the functions and responsibilities of government agencies clarifies why this is the most appropriate choice for the question posed.
