Of course jazz was VERY popular in the 1920s as it was at its big moments.

Speakeasies were originated from (1920-1933) so we have definite proof that those were of that time.

Flappers were a generation of young ladies in the 1920s from the West that usually wore short skirts, listened to jazz, etc.

So we have proof that the only plausible answer here is
   B : Football
