Time command is used to display and allow changes to the system time
Time format can be changed by changing in country setting in config.sys file
MS DOS displays the time in 12-hour or 24-hour format
All of above

The correct answer is D. All of above.

The TIME command is used to display and allow changes to the system time. The time format can be changed by changing the country setting in the config.sys file. MS DOS displays the time in 12-hour or 24-hour format.

Here is a brief explanation of each option:

  • Option A: The TIME command is used to display and allow changes to the system time. The syntax for the TIME command is TIME [/T]. The /T switch displays the current system time. Without the /T switch, the TIME command allows you to change the system time.
  • Option B: The time format can be changed by changing the country setting in the config.sys file. The country setting is located in the [COUNTRY] section of the config.sys file. The format of the time can be changed by changing the value of the HOUR_FORMAT and MINUTE_FORMAT variables.
  • Option C: MS DOS displays the time in 12-hour or 24-hour format. The default time format is 12-hour format. To change the time format to 24-hour format, you can use the /T switch with the TIME command.

I hope this helps!
