In a circus where performers share dressing rooms, training spaces and work in a fast-paced environment, the success of a show __________ fostering team-work and collaboration.

"Comes down to" means depends on in the end, so the success of the show depends on fostering teamwork. "Comes about" means happens and cannot take an object, "comes with" means is accompanied by, and "come along with" is ungrammatical after the singular "success".
