What are two Cisco Jabber 12.6 on-premises deployment types that can be run on a Windows- enabled PC? (Choose two.)

Cisco Jabber for Windows supports several on-premises deployment models. The "IM-only" mode provides core instant messaging and presence capabilities, connecting to the Cisco Unified Communications Manager IM and Presence Service. The "Full UC" mode offers a complete unified communications experience, integrating voice, video, voicemail, conferencing, and deskphone control, in addition to IM and presence. Both are distinct, officially documented on-premises deployment types for Cisco Jabber 12.6.

A. Contact Center Agent: This describes a user role or an integration with a contact center solution, not a fundamental Jabber deployment type.
C. multicloud-based: This is a cloud-based deployment model, which is explicitly excluded by the "on-premises" requirement in the question.
E. cloud-based: This is a cloud deployment model, which contradicts the "on-premises" requirement specified in the question.
