B. Repeated rhythm pattern

Explanation:

Ostinato is a term from music referring to a rhythmic pattern, part of a tune, or a complete melody that is repeated in the same musical voice and frequently in the same pitch as well. The word ostinato comes from Italian and means stubborn (similar to English obstinate), giving us a hint about the nature of this persistently repeating pattern. A famous example of ostinato is Carol of the Bells, composed by Ukrainian composer Mykola Leontovych.

answer; (binary). i believe this is the correct answer;

the answer is counterpoint.

counterpoint definition: "the art or technique of playing a melody or melodies in conjunction with another, according to fixed rules."

counterpoint is present in a lot of baroque music- such as bach (notably his wtc prelude and fugues) and scarlatti, but can also be found in music by mozart, beethoven. it can even be found in music as modern as john williams!
