And blues were the biggest influences on the development of jazz.
ragtime, rock
rock, bebop
band, ragtime
band, fusion

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.
