Suppose the time when the rear end of the train mects the entrance of the tunnei viewed from the ground and the train is tA and t'A, respectively, and the time when the front end of the train meets the exit of the tunnel viewed from the ground and the train is tB and t'B. Which of the following is incorrect? (A) In the frame of the ground, tA < tB. (B) In the frame of the train, t'B < t'A. (C) In the frame of the train, the duration from the train entering the tunnel and entirely get out of the tunnel is. (D) (E)t'A = t'B.
