Correct option is B
The train is 160 meters long and it takes 8 seconds to pass a man.
Speed = Distance / Time = 160 meters / 8 seconds = 20 meters per second.
Time = Total distance / Speed
= 360 meters / 20 meters per second
= 18 seconds.
The train needs to pass the entire length of the platform, so the total distance is the length of the train + the length of the platform.
Total distance = 160 meters + 200 meters = 360 meters.
