Accepted Answer

Virtual machines (VMs) can be created on a single physical machine using specialized software, allowing for multiple instances of operating systems and applications to run simultaneously. This optimizes the use of computing resources and provides flexibility in managing different environments on a single machine. Option A (Cloud based desktops) may be a subset of VMs but is not specific enough. Option B (Simulated desktops) is not a commonly used term in this context. Option C (Replicated workstations) is not accurate as it implies that each workstation is an exact copy of each other, which may not be the case in a virtualized environment.
