Which three statements are true about the behavior and configuration of GRUB on this system?

Examine some of the contents of the /boot/grub/grub.com file from an Oracle Linux system:
Default=0
Timeout=5
Splashimage=(hd0, 0)/grub/splash.xpm.gz

Which three statements are true about the behavior and configuration of GRUB on this system?

A.
(hd0, 0) represents the first partition on device /dev/hd0.

B.
The hiddenmenu directive hides the GRUB menu only for 5 seconds after which it becomes
visible again.

C.
The root directive specifies an initial root filesystem, allowing access to block device modules to
mount the real root filesystem on disk.

D.
(hd0, 0) represents the first partition on the first drive detected by the BIOS.

E.
The initrd directive specifies the initamfs, an initial root filesystem in RAM, allowing access to
block device modules to mount the real root filesystem.

F.
Each kernel must have an initramfs that matches the version of the kernel.

G.
Because there is an Unbreakable Enterprise Kernel installed, it must be the default kernel listed
as shown by the default=0 directive.
