D Correct answer
Explanation

Apparent magnitude measures how bright a star appears from Earth, which depends on both its intrinsic brightness (absolute magnitude) and its distance from us. A very bright star far away may appear dim, while a dim star nearby may appear bright. Size alone doesn't determine apparent brightness.
