Explanation / Answer

Answer: says that the orientation of the observer accounts for the differences among the types of AGNs.

The orientation of the torus and how it is seen from the observer’s vision is the prime way that creates differences and thus differentiation of various AGNs. AGN is the full form of Active Galactic Nucleus and refers to the bright area in the middle of the galaxy which also contains a supermassive black hole. The brightness at AGN is far greater than the stars that make up the galaxy itself and hence it is one of the most curious phenomenas that stays true to every galaxy ever discovered. Note: AGN’s includes quasars and hence option 3 is not valid.
