   An administrator needs to increase the size of a virtual disk for a Linux guest that is running out of space.

What is the next step to make the additional space available to the filesystem?

   • AResize the partition with fdisk or parted, then resize the filesystem.
   • BRun resize2fs on /dev/sda1 directly.
   • CReboot the guest to automatically detect the new disk size.
