What Is the Fundamental Difference Between Absolute and Apparent Magnitude

Multiple Choice

What is the fundamental difference between absolute and apparent magnitude of a star?

A) The difference is +5 since absolute and apparent magnitude differ by this value by definition.
B) Apparent magnitude depends on the star's temperature, whereas absolute magnitude is independent of temperature.
C) Apparent magnitude depends on the size of the star, whereas absolute magnitude is independent of this parameter.
D) Absolute magnitude is an intrinsic property of the star, whereas apparent magnitude depends on its distance from Earth.
