Pollock's method became known as "action painting" because A. it was used by the indians.
B. it showed people in action.
C. the artist moved around while doing it.

the answer is counterpoint.

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