It has been hard to define Jazz. This music style encompasses a wide range of music, starting at a period of over 100 years (ragtime) to the 2010-era, where rock plays and important role.
The correct option is: Ragtime, rock.
Ragtime was important style between 1897 and 1918. John Philip Sousa created this style through a modification of the popular march. He added extra polyrhythms inspired by African music.
I hope this is a helpful answer.
