Why each option
The /etc/inittab file controls SysV init behavior including the ctrl-alt-delete key combination handler.
/etc/keys does not exist as a standard Linux configuration file for key combination handling.
/proc/keys is a kernel keyring interface file used for cryptographic key management, not for remapping keyboard sequences.
In SysV init systems, /etc/inittab defines system initialization actions. The ctrl-alt-delete sequence is handled by a line with the 'ctrlaltdel' action keyword (e.g., ca::ctrlaltdel:/sbin/shutdown -r now), and commenting out or modifying that line disables or changes the behavior.
/proc/inittab does not exist; /proc is a virtual filesystem exposing kernel state, not configuration files.
/etc/reboot does not exist as a configuration file on standard Linux systems.
