Question 2

How is the energy that powers radio galaxies, quasars, and other active galactic nuclei produced?
 
  A) by matter that has been converted to pure energy by interacting with the jets shot out by a central black hole
  B) by nuclear fusion near a central black hole
  C) by matter-antimatter annihilation near a central black hole
  D) by magnetic fields that trap and accelerate charged particles, which then radiate large amounts of energy
  E) by gravity, which converts the potential energy of matter falling toward a central black hole into kinetic energy, which is then converted to thermal energy by collisions among the particles of matter
