All of the statements are consequences of Einstein's postulates. The first postulate states that the speed of light is constant in all inertial frames of reference, which implies statement A. The second postulate states that the laws of physics are the same for all inertial frames of reference, which leads to statements B and C (also known as time dilation and length contraction, respectively). The second postulate also implies statement D (also known as the relativity of simultaneity). Therefore, all of these statements are consequences of Einstein's postulates.
