a. guido darezzo
b. franco of cologne
c. philippe de vitry
d. an anonymous monk

Explanation:

Franco of Cologne was one of the first composers to develop and use clear rhythmic notation (Franco's notation) in medieval music, advancing rhythmic practices. Guido d’Arezzo is known for solmization (do - re - mi), Philippe de Vitry for isorhythm (later), and an anonymous monk doesn't fit this specific rhythmic notation innovation.

Answer:

B. Franco of Cologne
