Which command is used to see the version?

Answer: Option B

The Ver command in DOS is used to display the version number of the operating system that is currently running.

It typically displays the version information of MS-DOS or PC DOS installed on the computer.
The syntax is simply ver and when executed, it shows the version number of DOS.

Version is not a valid DOS command for displaying the version information of the operating system.

Verson is a misspelling and not a valid command in DOS.

None of above is incorrect because the Ver command is specifically used to display the version of DOS.

Therefore, the correct answer is Option B: Ver.
