The correct answer is C. See the disk volume label.
The vol command is a command-line utility that displays the volume label, serial number, and file system type of a disk volume. It can also be used to create or change a volume label.
The vol command is available in all versions of Windows. To use it, open a command prompt and type the following command:

For example, to display the volume label of the C drive, type the following command:
vol c:
The vol command will display the following information:
Volume in drive C is OS (C:)
Volume Serial Number is 1234567890123456

The volume label is a text string that identifies a disk volume. It is typically used to make it easier to identify different volumes on a computer. The volume label can be up to 11 characters long.
The serial number is a unique identifier for a disk volume. It is assigned by the manufacturer of the disk drive. The serial number can be used to identify a disk volume if it is lost or stolen.
The file system type is the type of file system that is used on a disk volume. The most common file systems are NTFS, FAT32, and exFAT. The file system type determines how data is stored on the disk and how it can be accessed.
