A Correct answer
Explanation

The watch gains 15 minutes in 24 hours. From 12:00 noon to 4:00 a.m. is 16 hours. The gain is (15/24) * 16 = 10 minutes. Thus, the watch shows 4:10 a.m.

AI explanation

From 12 noon to 4:00 am the following day, exactly 16 real hours pass. The watch gains 15 minutes uniformly over a 24-hour period, so over 16 hours it advances by an extra (15/24) times 16 minutes. This calculation results in exactly 10 extra minutes, meaning the watch will display 4:10 am.
