Explanation

Live migration (Option C) is the process of moving a running virtual machine from one physical host to another with zero downtime, allowing users to continue working without interruption. The VM's memory, storage, and network connections are transferred seamlessly between hosts while the machine remains operational.

• Option A (High Availability) is incorrect because it refers to systems designed to automatically restart VMs on another host after a failure occurs - it doesn't proactively move VMs with no downtime.
• Option B (Disaster Recovery) is incorrect because it focuses on restoring systems after a catastrophic event, not on seamlessly migrating live workloads.
• Option D (Multisite Replication) is incorrect because it refers to copying data across multiple geographic locations for redundancy, not moving a running VM between hosts.

Memory Tip: Think of "live" in live migration - just like a live TV broadcast keeps running without interruption, a live migration keeps the VM running while it moves. If you can watch it "live," there's no downtime!
