What year did US Congress ratify the 21st Amendment to repeal prohibition?

The 21st Amendment to the United States Constitution was ratified on December 5, 1933, marking the repeal of Prohibition, which had been instituted by the 18th Amendment in 1920. This amendment effectively restored the legal status of alcohol in the United States after more than a decade of prohibition, during which the manufacture, sale, and transportation of alcoholic beverages were largely banned. The significance of this event lies not only in its restoration of personal freedoms but also in its recognition of the difficulties and negative consequences that arose from enforcing such a ban on alcohol consumption. The other years mentioned are not associated with the ratification of the 21st Amendment, making 1933 the correct choice.
