While a "virtual appliance" (VM) could be deployed on Hyper-V, option C specifies XenServer, which is a native Citrix hypervisor often used in conjunction with other Citrix technologies like PVS.

The Synchronizer software, if it's a service component of a PVS server, should be installed within a virtual machine, not directly on the Hyper-V host operating system.

In a Citrix environment, components like the Provisioning Services (PVS) server, which often acts as a "Synchronizer" for vDisks, are typically deployed as virtual machines. Installing this "virtual appliance" (a VM running the PVS server software) on a XenServer (now Citrix Hypervisor) provides a robust and integrated platform for managing vDisks within the Citrix ecosystem.

Booting from an ISO image is part of the installation process for a virtual machine or physical server, not the deployment method for a running "virtual appliance."
