Which command is used to see the disk volume label?

Answer: Option B

The Vol command in DOS is used to display the disk volume label.

It shows the name or label assigned to a disk volume, which is typically set when the disk is formatted or labeled.
The syntax is simply vol and when executed, it displays the volume label of the current drive.

Ver is used to display the version of DOS that is currently running, not the disk volume label.

Version is not a valid DOS command for displaying the disk volume label.

Volume is not a valid DOS command for displaying the disk volume label.

Therefore, the correct answer is Option B: Vol.
