The systems department of Chandrabhaga Urban Bank runs two kinds of virtualised host. Upon the rst, a thin layer of software is installed directly upon the bare metal of the server, owns the hardware and schedules the guest operating systems itself; there is no other operating system beneath it. Upon the second, which is used by the developers upon their own desktops, Windows is installed in the ordinary way and the virtualisation product is then installed upon Windows as one more application among many, so that the guests it runs obtain their processor time and their memory through the host operating system rather than in place of it. The second of these arrangements is a type-2 hypervisor, which is correctly described as:

1. AA bare-metal hypervisor, which is installed directly upon the hardware and requires no host operating system beneath it
2. BA hypervisor that may run only guests of the same operating system as the host, paravirtualisation being unavailable to it
3. CA hosted hypervisor, which runs as an application upon a conventional host operating system and depends upon that host for access to the hardware — VMware Workstation and Oracle VirtualBox being the familiar instancesCorrect
4. DA hypervisor that shares one kernel among all its guests, each guest receiving an isolated view of that single kernel
5. EA hypervisor that runs within the rmware of the server and is loaded before the boot loader
