Why each option
The 'config-register' command modifies the 16-bit configuration register value that controls how a Cisco router boots.
The 'config-register' command is the correct Cisco IOS syntax for changing the configuration register stored in NVRAM. This value determines the router's boot sequence, including whether it loads IOS from Flash, boots to ROM Monitor, or ignores the startup-config, and the change takes effect after the next reload.
'configuration-register' is not a valid Cisco IOS command and will be rejected by the CLI parser.
'conf-register' is not a recognized Cisco IOS command abbreviation for this function.
'config-registration' does not exist in Cisco IOS syntax and will produce an error.
