Quizplus · Accepted Answer

In a uniformly expanding universe, all galaxies appear to be moving away from each other due to the expansion of space. This means that the farther away a galaxy is from Galaxy C, the faster it appears to be moving away. Therefore, as viewed from Galaxy C, all other galaxies will appear to be moving away from itself, and the speed at which they are receding will be proportional to their distance. Thus, the correct choice is C.
