D Correct answer
Explanation

Next train at 18:00 hr. Train leaves every 2.5 hours (2 hours 30 minutes). Previous train left at 18:00 - 2:30 = 15:40 hr. Announcement made 40 minutes after previous train left: 15:40 + 0:40 = 16:20 hr. None of the given options (15:30, 17:10, 16:00) match 16:20, so the answer is "None of these."
