If the speed of light were not absolute, it would mean that different observers would measure different speeds for light. In the case of a binary star system, the speed at which light from a star comes towards the Earth would depend on the position and velocity of the star relative to Earth. Therefore, choice A is the best option. The distance, masses, and sizes of the stars may also affect how the binary system behaves, but they wouldn't have a direct impact on the speed of light.

If the Speed of Light Were Not Absolute, the Speed
