According to the theory of relativity, time dilation occurs when an observer is moving at a significant fraction of the speed of light relative to another observer. However, in this scenario, both spacecraft are moving at the same speed, so there is no relative motion between the two. Therefore, each observer will see the other clock running at the same rate as their own clock. Hence, option B is correct.
