B Correct answer
Explanation

In high-availability configurations, when a node running a service process becomes unavailable, the service automatically migrates to another available node. This process is called failover - it's distinct from recovery (retrying on same node) and resilience (general ability to withstand failures). Failover ensures continuous service availability despite node failures.
