Which of the following is an example of administrative liability?

Administrative liability refers to the responsibility that can arise from failing to adhere to laws and regulations governing the sale and serving of alcohol. Such liabilities typically result in administrative actions taken by government agencies rather than criminal penalties.

The most fitting example of administrative liability among the options provided is license revocation. This indicates that a business or individual has lost their right to operate legally due to noncompliance with regulatory standards. License revocation serves as a direct consequence of failing to meet the legal requirements of serving alcohol, which can be enforced by local or state licensing boards.

Fines, while also a form of penalty, are generally monetary consequences rather than changes to one's operational status. Community service is often associated with criminal liability or public service requirements, while imprisonment pertains to severe criminal penalties typically reserved for more serious offenses. License revocation specifically encompasses the administrative aspect that directly affects one's ability to legally conduct business, aligning it perfectly with the concept of administrative liability.
