What does the time "1:00 am" convert to in military time?

In military time, the hour is represented on a 24-hour clock system, where times from 1:00 am to 11:59 am are generally expressed by adding a leading zero if necessary. Therefore, 1:00 am converts directly to 0100 hours in military time.

This conversion is straightforward as the hour remains the same; however, a leading zero is added to indicate that it is a time in the early morning hours. The format follows a consistent pattern where the first two digits represent the hour and the succeeding two digits represent the minutes. Hence, 1:00 am is represented as 01:00, which is simplified in military time to 0100.

In a broader context, other times throughout the day would also follow this pattern, with noon being represented as 1200 and midnight as 0000. The other choices do not adhere to the correct military time representation for 1:00 am, which reinforces that 0100 is the accurate conversion.
