B Correct answer
Explanation

Train A starts at 10 am and travels alone for 1 hour until 11 am, covering 65 km. At 11 am, remaining distance = 465 - 65 = 400 km. Both trains now move toward each other at combined speed 65 + 35 = 100 km/hr. Time to meet = 400/100 = 4 hours after 11 am, which is 3 pm. Option A (2 pm) would result from incorrectly calculating remaining distance or relative speed.
