Why each option
In SysV init systems, the /etc/inittab file is modified to control system actions, including disabling the Ctrl-Alt-Delete key combination.
/etc/keys is not a standard SysV init configuration file for key combination actions.
/proc/keys is a virtual file providing information about kernel keyrings, not for configuring system behavior.
The /etc/inittab file is the primary configuration for SysV init, where entries like 'ca::ctrlaltdel:/sbin/shutdown -t5 -r now' define actions for the Ctrl-Alt-Del key sequence; commenting or removing this line disables the action.
/proc/inittab does not exist as a configuration file for SysV init; configuration is in /etc/inittab.
/etc/reboot is not a standard SysV init configuration file used to disable the Ctrl-Alt-Delete key combination.
