What amendment repealed prohibition in the United States?

The 21st Amendment is the correct answer because it specifically repealed the 18th Amendment, which had established Prohibition in the United States. The 18th Amendment, ratified in 1919, prohibited the manufacture, sale, and transportation of alcoholic beverages. This led to a range of social and legal challenges, including the rise of illegal speakeasies and organized crime related to alcohol smuggling. After ongoing public dissatisfaction with the effects of Prohibition, the 21st Amendment was ratified in 1933, officially reversing the earlier ban and allowing for the legal production and sale of alcohol once again. This amendment reflected a significant shift in public policy regarding alcohol consumption in America and marked the end of a notable chapter in U.S. history.
