C Correct answer
Explanation

To completely cross the platform, the train must cover the platform length (500m) plus its own length (200m) = 700m total distance. Speed = 70 km/h = 70 × (1000/3600) = 19.444 m/s. Time = 700/19.444 = 36.066 seconds. Adding 30 min stop + 36 sec to 4:00 pm gives 4:30:36 pm.
