### Solution:

Concept: In this question, we are going to find out the distance using the relation of speed, time and distance.
Given,
Speed of train = 60 km/hr
Time taken to cross= 30 sec = 1/120 hour
Now, the length will be equal to the distance.
So,
So, the Length of train is ½ hour= 500m
Hence, the correct option is 4.
