B Correct answer
Explanation

Speed = Distance / Time = 120 / 2 = 60 m/s. Time to cover 240 m = 240 / 60 = 4 s.

AI explanation

Using the basic speed formula, Speed = Distance / Time, the train's uniform speed is 120 m / 2 s = 60 m/s. To find the time to cover 240 m, rearrange the formula to Time = Distance / Speed. This gives 240 m / 60 m/s = 4 s.
