Quizplus · Accepted Answer

Special relativity theory predicts that the notion of simultaneity is relative to the observer's reference frame. Events that are simultaneous in one inertial reference frame may not be simultaneous in another inertial reference frame. Therefore, option C is the correct answer. The other options are incorrect because they imply that simultaneity is absolute or depends only on a limited set of conditions.
