Explanation:Definition of Midnight:
Midnight is defined as the middle of the night, specifically 12 o'clock at night. It is the point at which one day ends and another begins.
Time Notation:
The time notation system uses a 12-hour clock, which divides the day into two periods:
1. AM (ante meridiem), which means "before noon" and includes the time from midnight to noon (12 a.m. to 11:59 a.m.).
2. PM (post meridiem), which means "after noon" and includes the time from noon to midnight (12 p.m. to 11:59 p.m.).
Options:
To determine the correct answer, let's analyze each option:
Option A: 12 a.m.This option indicates that it is midnight. The "a.m." stands for "ante meridiem," which means "before noon." Since midnight is the beginning of a new day and occurs before noon, this is the correct answer.
Option B: 12:05 a.m.This option indicates a time five minutes past midnight. While it is early in the morning, it is not precisely midnight, so it is not the correct answer.
Option C: 12 p.m.This option indicates noon, which is the middle of the day. Since midnight is the middle of the night, this is not the correct answer.
Option D: 12:05 p.m.This option indicates a time five minutes past noon. It is definitely not midnight, so it is not the correct answer.
Conclusion:
Based on the definitions of midnight and the time notation system, the correct answer is
Option A: 12 a.m. This represents the time exactly at midnight, signifying the start of a new day.
