The best measure of a star's brightness is **B) apparent magnitude**. Apparent magnitude measures how bright a star appears from Earth, taking into account its distance and intrinsic luminosity. Absolute magnitude, while important for understanding a star's intrinsic brightness, relates to its brightness at a standard distance (10 parsecs), whereas apparent magnitude reflects the brightness observed from our perspective.
