Which amendment repealed Prohibition in the United States?

The Twenty-First Amendment is the correct answer because it specifically repealed the Eighteenth Amendment, which had established Prohibition in the United States. Prohibition, enacted in 1920, prohibited the manufacture, sale, and transportation of alcoholic beverages. The effects of Prohibition led to widespread lawbreaking and the rise of organized crime, prompting a change in public sentiment regarding alcohol consumption. In 1933, the ratification of the Twenty-First Amendment marked the end of Prohibition, effectively restoring the legality of alcohol and allowing for federal regulation of its sale.

The other amendments listed do not pertain to Prohibition. The Eighteenth Amendment actually enacted Prohibition, while the Sixteenth Amendment relates to the federal income tax, and the Twenty-Third Amendment grants electoral votes to the District of Columbia in presidential elections. Thus, the Twenty-First Amendment is highlighted as the pivotal change that repealed the earlier ban on alcohol, reflecting a significant shift in American legal and social landscapes.
