If a food establishment serves alcoholic beverages, what sign is required to be displayed?

In a food establishment that serves alcoholic beverages, displaying an "Alcohol and Pregnancy Warning" sign is essential to inform patrons about the potential risks associated with alcohol consumption during pregnancy. This warning serves an important public health role by educating customers about the dangers of consuming alcohol while pregnant, which can lead to serious health consequences for the developing fetus, such as fetal alcohol spectrum disorders. By prominently displaying this warning, the establishment is taking a responsible approach to customer safety and public health.

The other options, while relevant to responsible alcohol service and consumption, do not specifically fulfill the requirement related to health warnings about pregnancy. Thus, the "Alcohol and Pregnancy Warning" sign is the most appropriate and necessary choice for food establishments that serve alcoholic beverages.
