Why each option
The 'voice service voip' command must be entered on a Cisco IOS router to access VoIP service configuration mode and enable SIP support for SIP endpoints under CUCME.
'telephony-service' is the CUCME configuration command used for SCCP-based IP phone registrations and CME dial-plan settings, and it does not enable SIP endpoint support.
'ip voice' is not a valid Cisco IOS configuration command and does not exist in the CUCME configuration hierarchy.
'voice plan' is not a valid Cisco IOS command and has no role in enabling voice or SIP features under CUCME.
The 'voice service voip' command enters the global VoIP service configuration context, within which the 'sip' sub-command activates SIP signaling processing. This is the required configuration path on Cisco IOS routers running CUCME to register and support SIP-based endpoints, as it initializes the SIP protocol stack at the platform level.
