E)form small irregular galaxies.

Question

Quizplus · Accepted Answer

The merger theory suggests that the brightest active galactic nuclei are the result of mergers between galaxies, which can lead to the formation of supermassive black holes. Therefore, the best choice is D - containing supermassive black holes. The merger theory proposes that the bright activity observed in active galactic nuclei is due to the accretion disk around a supermassive black hole at the center of a galaxy formed by the merger of two smaller galaxies. Therefore, the brightest active galactic nuclei should contain supermassive black holes.
