What characteristic of some radio lobe galaxies contributes to the idea that their energy emission is intermittent?

    They emit continuous pulses of energy that peak at regular intervals.
     They display "blobs" of material along their lobes that indicate this material was ejected in bursts.
     They change direction in space at variable intervals.
     They are seen to turn on and off at regular intervals when observed in infrared wavelengths.
     They are surrounded by regularly spaced concentric rings of material.
