Correct Answer: ABD
Explanation/Reference:
A: GRUB requires only the file name and drive partitions to load a kernel. You can configure this information by editing the /boot/grub/grub.conf file, by using the GRUB menu, or by entering it on the command line.
Incorrect: not C: If you have set a GRUB password, you must press P and enter the valid password to be able to edit the titles or change kernel boot parameters.

If you press E, select the root, kernel, or initrd directive, and press E to edit it.
Not E: Grub can be password protected, but not individual functions.
