20 to 15

Answer 1

In the Hertzsprung-Russell (H-R) Diagram, blue stars are typically among the most luminous. The brightest blue stars, which are found in the upper left corner of the H-R Diagram, tend to have an absolute magnitude in the range of approximately -15 to -20. Therefore, the correct option for the brightness of a blue star in the upper left corner would be -15 to -20.
