F. Run the systemctl reload systemd command

Correct Answer: A,B

Explanation
To make the third menu entry of your GRUB2 boot menu your default menu selection, you need to do the following tasks:
Edit the /etc/default/grub file and set GRUB_DEFAULT to 2
Run the grub2-mkconfig command
The /etc/default/grub file contains various settings for the GRUB2 boot loader, such as the default menu entry, the timeout value, the theme file, etc. The GRUB_DEFAULT setting can be set to a numeric value that corresponds to the menu entry index (starting from 0), or a string value that matches the menu entry title. The grub2-mkconfig command will generate a new /boot/grub2/grub.cfg file based on the settings in
/etc/default/grub and other configuration files and scripts. References:
