Why each option

In a Cisco Jabber hybrid cloud deployment with Webex Platform Service, call control for voice calls remains on the on-premises CUCM, not in the cloud.

AVoice calls use Webex Calling platform for call control and use hybrid media nodes for local

Webex Calling is a separate cloud calling product and is not the call control platform used in a Jabber hybrid deployment backed by on-premises CUCM.

BVoice calls use local media nodes to keep traffic internal for internal traffic and use Webex

Local media nodes are used for media optimization in Webex meetings, not for call control in a CUCM-based Jabber hybrid deployment.

CVoice call use Cisco Unified Communications Manager for local calls and Webex Calling for

A split where CUCM handles local calls and Webex Calling handles other calls does not reflect the architecture of a standard Jabber hybrid deployment with on-premises CUCM.

DVoice calls use local Cisco Unified Communications Manager for all calls.Correct

In a hybrid cloud deployment, Cisco Unified Communications Manager remains the call control engine for all voice calls - both internal and external. Webex Platform Service in this context provides messaging and presence capabilities, while CUCM retains ownership of SIP registration and call routing for voice traffic.
