Absolute brightness is the actual amount of light produced by the star, whereas apparent brightness changes with distance from the observer the following statement describes absolute and apparent brightness. The correct option is D.
A star's real energy production is measured in terms of absolute brightness, although our perception of that energy depends on our viewing distance. In order to comprehend the nature of stars, their wide range of distances, and their observed brilliance in the night sky, it is essential to make this distinction.
The exact amount of light energy emitted from the surface of a star is referred to as its absolute brightness. It represents the amount of energy the star generates in a given amount of time because it is a measurement of the star's intrinsic brightness. Consider absolute brightness as the star's overall "brightness power," regardless of the observer's distance from it.
Thus, the ideal selection is option D.
