B Correct answer
Explanation

The clock loses 16 minutes in 24 hours. When the clock shows 5 a.m. the next day, 24 hours have passed on the clock, but the actual time is 24 hours + 16 minutes.

AI explanation

The clock loses 16 minutes in 24 hours, so if it indicates 5:00 am the next day, it has exactly run for 24 faulty hours. The true elapsed time is calculated as (24 hours * 1440 minutes) / (1440 - 16 lost minutes), which equals 1440 / 89 times 24. This evaluates to 24 hours and 16 minutes, meaning the actual time is 5:16 am.
