PLEASE HELP OH MY GOD ILL LOVE YOU FOREVER

1. Why would Cygnus x-1, a black hole with an estimated mass of 14.8 solar masses, NOT be an example of a supermassive black hole?

supermassive black holes must have a solar mass of tens to hundreds of millions of solar masses, so this black hole's mass is too small to be a supermassive black hole.

supermassive black holes are only names by a random string of numbers and letters (like a license plate), not words, so this cannot be a supermassive black hole

this black hole does not have a quasar at its center, so it cannot be a supermassive black hole.

Cygnus x-1 is not at the center of its galaxy (the milky way), so it cannot qualify as a supermassive black hole.
