D Correct answer
Explanation

Speed in m/s is $60 imes (5/18) = 50/3$ m/s. Distance (length of train) = Speed $ imes$ Time. So, $(50/3) imes 9 = 150$ meters. The other options (112, 120, 130) do not match the calculation based on the standard physics formula for a train crossing a stationary point.
