Which of the following is NOT a function of administrative agencies?

Administrative agencies play a crucial role in the functioning of government by implementing and enforcing laws. One of their primary functions is enforcement of laws, ensuring compliance with regulations established by legislative bodies. They are also involved in rule-making, where they develop detailed regulations that clarify and implement the statutes passed by lawmakers. Additionally, administrative agencies adjudicate disputes, providing a forum for resolving conflicts that arise under the laws and regulations they enforce.

Public relations campaigns, while they may be undertaken by some agencies to promote understanding or compliance with certain laws or regulations, are not considered a formal function of administrative agencies. These campaigns are not essential to the agencies' primary roles of enforcement, rule-making, or adjudication, and thus do not align with the core responsibilities that define the purpose of these agencies.
