Quizplus · Accepted Answer

According to the theory of special relativity, two observers can share the same space and time measurements in two cases: when they are at rest relative to each other (option A) or when they are moving at a constant velocity relative to each other (option B). Therefore, either of these options (option C) is the best choice. Option D is incorrect because there are two cases where observers can share the same space and time measurements.
