How is 5:00 AM written in military time?

In military time, the 24-hour clock system is used, which eliminates the need for "AM" and "PM" designations. The hours are represented in a two-digit format, where midnight is 0000 and the hours progress through to 2400.

To convert 5:00 AM into military time, you simply take the hour (5) and represent it as 0500, ensuring that there are four digits in total. The leading zero is included because military time always maintains a two-digit format for both the hour and the minute components. Therefore, 5:00 AM is correctly represented as 0500 in military time.

The other options represent either different times or incorrectly formatted military times, which are not applicable in this case.
