Material is seen to be ejected from many active galaxies in two intense and oppositely directed jets. What gives rise to this ejection?

(a)   Pressure in an accretion disk around a supermassive black hole at the center of the galaxy. The pressure forces matter outward, perpendicular to the disk.
(b)   Pressure inside the singularity at the center of a supermassive, rotating black hole in the core of the galaxy. The matter is ejected along the rotation axis of the singularity.
(c)   A supermassive binary black hole at the center of the galaxy. As the two black holes orbit around each other, matter is ejected perpendicular to the orbit.

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
