Answer:
C
Step-by-step explanation:
A star does not necessarily get brighter or dimmer when you get closer to it. The apparent brightness of a star is determined by both its intrinsic luminosity (how much energy it emits) and its distance from Earth. If you move closer to a star, the distance between you and the star decreases, so the apparent size of the star increases. However, if the intrinsic luminosity remains the same, the net effect on brightness will be negligible. On the other hand, some stars may appear to change in brightness due to atmospheric effects, such as scintillation and atmospheric extinction, which can affect the amount of light that reaches Earth and how it is perceived.
