Which of the following best identifies a difference between apparent magnitude and luminosity in stars?
Group of answer choices

Luminosity is always given as a numerical value; apparent magnitude has no numeric value.

The luminosity of a star will remain constant over the life of a star, but its apparent magnitude will change daily.

The measurement of the luminosity of a star depends on the position of the observer; apparent magnitude does not.

Two stars can have the same luminosity but different apparent magnitudes, depending on how far away they are.
