All of the musical styles you mentioned—gospel, dixie, blue (likely referring to blues), and jazz—have played a significant role in shaping current music genres. However, if we have to choose one that has had a particularly profound influence on a wide range of modern music, it would be D. jazz.
Jazz not only laid the foundation for many contemporary genres, such as rock, pop, hip-hop, and electronic music, but it also introduced unique elements like improvisation and syncopation that are prevalent in various modern musical styles. That said, each of the other styles has had considerable influence as well.
