B Correct answer
Explanation

Time from Monday 8 AM to Tuesday 10 PM = 24 + 14 = 38 hours. 38 hours = 2280 minutes. The watch gains 5 seconds every 3 minutes. Total gain = (2280 / 3) * 5 = 760 * 5 = 3800 seconds. 3800 seconds = 63 minutes and 20 seconds. 10:00 PM + 1 hour 3 minutes 20 seconds = 11:03:20 PM.
