Final answer:
Prohibition persisted during the 1920s despite increased public opposition and widespread non-compliance, but was eventually repealed in 1933 due to its ineffectiveness. Therefore, the correct option is A.
Step-by-step explanation:
Prohibition continued throughout the 1920s in spite of increased public opposition. The era saw a significant rise in activities that openly defied the prohibition law, including the illegal liquor trade by organized crime and gangsters such as Al Capone. Despite the passage of the Eighteenth Amendment and the Volstead Act to enforce prohibition, the government had difficulty funding enforcement efforts, and there was widespread non-compliance across the country. By the end of the 1920s, the ineffectiveness of prohibition became apparent, and the law was eventually repealed in 1933.
