I gave my students this multiple choice question: Which statement correctly describes a relationship between the distance from Earth and a characteristic of a star?

Only one answer is correct among these 4 choices:
- As the distance from Earth to the star decreases, its size increases.
- As the distance from Earth to the star increases, its size decreases.
- As the distance from Earth to the star decreases, its apparent brightness increases.
- As the distance from Earth to the star increases, its apparent brightness increases.

Could you tell me which one is correct?

As the distance from Earth to the star decreases, its apparent brightness increases.
