Answer 1

In the Hertzsprung-Russell (H-R) Diagram, blue stars are typically very hot and luminous. They are found in the upper left corner of the diagram, where stars are both massive and bright. The brightness (absolute magnitude) of these blue stars usually falls in the range of -15 to -20.

Therefore, the correct response is:

-15 to -20
