What is the 24-hour representation of 3:00 AM?

• A. 0030
• B. 0330
• C. 300
• D. 0300

Answer: (D)

In 24-hour time, you write the time as four digits: the first two are the hour (00–23) and the last two are the minutes. For 3:00 AM, the hour is 3, so you pad a leading zero to get 03, and the minutes are 00. Put it together as 0300. That matches the standard four-digit format and the actual time. The other options would represent different times or use an invalid four-digit form: 0030 is 00:30 (midnight plus thirty), 0330 is 03:30, and 300 lacks the required leading zero for the hour.
