A-1, B-2, C-3, D-4 Explanation: A. Type-1 Hypervisor -> 1: A Type-1 (bare-metal) hypervisor runs directly on the underlying physical hardware without needing a host operating system beneath it (e.g., VMware ESXi, Xen). B. Type-2 Hypervisor -> 2: A Type-2 (hosted) hypervisor runs as a standard software application on top of an existing host operating system (e.g., Oracle VirtualBox, VMware Workstation). C. Para-virtualization -> 3: In para-virtualization, the guest operating system is modified so that it is aware of the hypervisor and issues direct hypercalls instead of executing non-virtualizable CPU instructions. D. Full Virtualization -> 4: Full virtualization allows an completely unmodified guest operating system to run directly by using techniques like binary translation or hardware-assisted virtualization to interce
