B. 21st Amendment.
Step-by-step explanation:
The 18th Amendment banned the production, sale, and distribution of liquor. The 21st Amendment repealed the 18th Amendment and made the production, sale, and distribution of liquor legal again.
The 18th Amendment banned alcohol and many people had mixed feelings about it. The temperance movement was essentially against alcohol, wanting it to be banned and prohibited. Many of the people in the temperance movement were women, some of them being victims of domestic violence which they would say was brought on by alcohol.
The banning of alcohol didn't stop a lot of people from obtaining it. Many people would make it from home illegally, or smuggle it in from other countries. Sometimes the police would become corrupt, taking bribes because of liquor. The 18th Amendment proved to be pretty ineffective, many local governments barely taking action to enforce it. Eventually, the 21st Amendment would be ratified, getting rid of the ban on alcohol.
