D) all of the above

Question

Quizplus · Accepted Answer

Active galactic nuclei (AGNs) typically have orbiting clouds of gas and dust that emit light at specific wavelengths, creating emission lines in their spectra. Without these clouds, an AGN would lack these characteristic emission lines, differentiating it from a typical quasar, which is a type of AGN known for its strong emission lines. The presence of a jet or variability does not depend on the orbiting clouds.
