E Correct answer
Explanation

To determine if the train can reach Patna before 9:00 pm, we need the distance from Delhi to Patna and travel time information. Statement I only gives an upper bound on speed (<70 km/hr), not the actual speed. Statement II gives the total Delhi-Kolkata distance (>825 km), not the Delhi-Patna distance. Statement III only tells us the train stops 5 times, but not how long each stop takes or where Patna is located. Since none of the statements provide the distance to Patna or actual travel time, the data is insufficient to answer the question. Therefore, option E (None of these) is correct.
