Explanation
Path Monitoring (C) is correct because it actively tests reachability to a specific destination IP address, allowing the virtual router to verify that a particular network path is actually usable before routing traffic over it.
Heartbeat Monitoring (A) checks whether a peer device is alive (typically via keepalive messages between redundant devices), but it does not test reachability to a specific destination IP. Failover (B) is the action that occurs when a failure is detected - it's the result of monitoring, not the monitoring mechanism itself. Ping-Path (D) is a plausible-sounding distractor but is not a standard virtual router feature name.
Memory tip: Think of "Path Monitoring" literally - it monitors a path to a destination. If you need to know whether you can reach a specific IP, you monitor the path to it.
