Hi!

The correct answer is B.

Explanation

Astronomers use both apparent magnitude and absolute magnitude to define how bright a star is. By way of apparent magnitude, astronomers gauge how bright the star seems from the Earth, and b way of absolute magnitude, astronomers gauge how bright the star seems from 10 parsecs/32.6 light years which is a set standard distance.

Hope this helps
