What is an objective in developing policies for serving alcoholic beverages to the public?

Developing policies for serving alcoholic beverages to the public is important for maintaining a safe and responsible environment for drinking. Option A, improving the dance floor, and option B, enhancing the lighting, are not relevant to the question as they do not directly address the issue of alcohol service. Option D, offering the cheapest drinks, may attract a larger crowd, but it does not address the responsibility of serving alcohol. Option C, preventing alcohol service to minors, is the correct answer as it is a necessary objective in order to comply with laws and regulations, protect minors from underage drinking, and prevent potential legal and safety issues.
