Answer
A
X: speed of light is always 3.0 meters meters per second Y: applies to objects moving almost at the speed of light Z: describes the effect of constant motion in space on time
B
X: laws of physics are the same for all uniformly moving frames of motion Y: applies to objects with constant velocity Z: speed of light through empty space is the same for all observers
C
