A Correct answer
Explanation

In Linux device numbering, the major number identifies the device type and driver to use (e.g., major 3 for IDE hard drives, major 8 for SCSI disks). The minor number identifies the specific device instance (like which partition). When you access /dev/hda, the kernel uses the major number to find the correct driver and the minor number to determine which specific device.
