Answer:a) Bob Fosse
Step-by-step explanation:
Bob Fosse may have been the most influential choreographer-director of the second half of the 20th century in Broadway.
All of what Fosse showed on stage was cynical and dark. The film fantasy-bio of his own life, All That Jazz, in which he was the writer, director and choreographer dripped cynicism and bleakness.
His dance (Fosse-dance) featured muscle isolations, cynicism, contempt and sexuality. He used staccato movements and erotic suggestions to stage dance numbers. As his career advanced,his interest grew in expressing sexuality and decadence with dance.
