Answer:
A) Chorale
Explanation:
As part of his set of reforms, Martin Luther (1483-1546) advocated changes in masses and celebrations to give more space to church sung music, defining choirs as an integral part of spiritual experience.
The decision led to an evolution of corals in Germany. The famous cantatas Johan Sebastian Bach (1685-1750) were taken from Luther's philosophy, though more than 100 years later.
