Which statement is included in the IMO Warnings standards?

In IMO Warnings standards, monitoring and alerting cover the main risk indicators a navigator needs to see on ARPA radar. Guard rings or guard zones are virtual safety areas around your own vessel; they alert you when another vessel intrudes into a region where a collision risk is possible, helping you keep maintaining safe separation. CPA range and CPA time warnings are about the predicted closest point of approach: when the calculated distance or the time to reach that point falls within defined risk thresholds, the system issues a warning so you can take action before a potential collision. A lost target warning signals that the radar tracking has dropped the target and it can no longer be reliably monitored, prompting you to re-acquire or re‑track it. Since all of these types—guard rings/zones, CPA range/time, and lost target—are included in the warning standards, the option that encompasses all of them is the correct one.
