Answer:
The correct answer is: Jazz.
Step-by-step explanation:
Jazz music was extremely popular during the years of prohibition (1920's to 1930s) and it was part of the underworld.
Jazz was commonly played live in speakeasies, which were underground places dedicated to the selling and consumption of alcoholic beverages. In these places, people went to relax, drink alcohol, and "speak-easy" during the prohibition years.
Jazz music was then associated with illegal and inmoral activities and it started to generate the genre's reputation for threatening the country's cultural values.
In conclusion, the correct answer is: Jazz.
