Which of the following corresponds to 4:00 AM in military time?

In military time, the 24-hour clock system is used, where the hours from midnight (00:00) to 11:59 AM are represented with the same numbers as on a standard clock but without the AM designation. For times from 1:00 AM to 12:59 PM, the hour is expressed in a four-digit format.

0400 corresponds directly to 4:00 AM because "04" indicates the hour and "00" indicates the minutes, thus accurately representing the time in a 24-hour format. The military format eliminates the need for AM or PM designations, relying solely on the hours and minutes.

Other options represent times that either fall later in the morning or have different minute values attached, making them incorrect as they do not correspond to 4:00 AM in military time.
