10 to 5

Answer 1

In the Hertzsprung-Russell (H-R) Diagram, blue stars are typically found in the upper left corner, indicating that they are very hot and also very luminous. The absolute magnitude of these stars generally falls within the range of -15 to -20.

So the correct choice is:

-15 to -20.
